Mixed race children suffer from more health problems:
Race mixing leads to outbreeding depression & pairings of non-complementary traits.
A massively well-funded study of over 100,000 school children found that “Adolescents who identify themselves as mixed race are at higher health and behavior risk than those of 1 race.” Indeed, even when controlling for education, socioeconomic status, and other factors, there is an across-the board higher rate of health risks amongst mixed race adolescents than mono-racial adolescents.

Often race-deniers will bring up Haldane’s rule, arguing that since races can mix and create fertile offspring, the genetic distance is not too great. Haldane’s rule is “when in the offspring of two different animal races one sex is absent, rare, or sterile, that sex is the heterogametic [XY] sex.”

Race Is A Social Construct?
The Immune System: How Important Is Race?
>"If Nick Glasgow were white, he would have a nearly 90 percent chance of finding a matching bone marrow donor who could cure his leukemia."
The reason that mixed-heritage patients are so hard to match can be found in the immune system. Different races have developed certain proteins, or markers, that are part of the body's natural defenses. These markers help the immune system determine which cells are foreign and should be rejected.
Are cells racist?
A match between two people who share more genetically in common significantly reduces the risk of the donor and recipient cells attacking each other. (READ: cells from people of two different races will attack and fight each other as though they are a virus)
The more people of different backgrounds who produce offspring = the more types that are harder to match.
Multiracial patients have uncommon profiles and since there can be many possible racial and ethnic combinations in multiracial societies, finding a match can still be extremely difficult.

As an example, a White mother of mixed-race child would have more genetically in common with a random White person on the street than with her own child.
If such a dramatic and fundamental alienation from your own parents if not horrific enough, With a mixed-race child diagnosed with leukemia, every member of the child's own family becomes an incompatible donor for a bone-marrow transplant, and finding a compatible donor is unlikely:
One obstacle to finding a matching donor was her mixed ethnic background. Her father is black, with West Indian and Panamanian roots. Her mother is white, with Russian-Jewish roots. In addition, only 5 percent of registered donors are black.

The Race for Ancestral Genetics in Clinical Trials
>A seasoned cancer researcher would never set up a study in which all the ill patients were, say, Canadian, and all the healthy controls were Japanese. And yet cancer researchers risk making a similar mistake if they overlook genetic information that fleshes out what many of us like to think of as race or ethnicity, some experts say.
>Fortunately, awareness of how ancestral genetics might contribute to risk of disease and drug response in people has risen over the last several years. Studies that look directly at the problem are on the rapid rise, and this increased interest has biotechnology companies lowering the cost of tests that determine genetic ancestry, thanks to a little competition. However, experts have yet to decide on how to genetically define ancestry, suggesting examining anywhere from a handful to hundreds of gene variants.
>Not including information on the race or ethnicity of study volunteers could skew disease risks as stronger or weaker than they really are.
>"Alzheimer's disease is the poster child for this problem," says pharmacogeneticist Esteban Burchard, M.D., of the University of California in San Francisco. A variant of the gene ApoE4 is a strong genetic risk factor for early-onset Alzheimer's disease, and the characteristic most likely to raise or lower that risk is race.
>"It occurs in about 20% of the African American population, and it means nothing. It occurs in about 6% of the Japanese, and it makes their risk six times higher [than that for white people]," Burchard said. "Something about being Japanese unleashes the wrath of the gene, and something about being African American attenuates it."

Sickle cell anaemia is a condition found almost exclusively in blacks, about 1 in 4 west Africans carry the gene for it, almost no whites do. Any whites who carry the gene most likely have a black ancestor.
As a result of population growth in African-Caribbean regions of overseas France and immigration from North and sub-Saharan Africa to mainland France, sickle cell disease has become a major health problem in France. SCD has become the most common genetic disease in this country.

Invasive species: Genes Are Destroyed With Admixture/Racial Mixing
Extinction by hybridization:
>Non-indigenous species can bring about a form of extinction of native flora and fauna by hybridization and introgression either through purposeful introduction by humans or through habitat modification, bringing previously isolated species into contact. These phenomena can be especially problematic for rare species coming into contact with more abundant ones. Increased use of molecular techniques focuses attention on the extent of this under-appreciated problem that is not always apparent from morphological observations alone. Some degree of gene flow is a normal, evolutionarily constructive process, and all constellations of genes and genotypes cannot be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.

The Island Model with Stochastic Migration:
>It is supposed that the migration rate and the immigrant gene frequency are independent of each other in each generation, and each of them is independently and identically distributed in every generation. The treatment is confined to a single diallelic locus without mutation. If the diploid population is infinite, selection is absent and the immigrant gene frequency is fixed, then the gene frequency on the island converges to the immigrant frequency, and the logarithm of the absolute value of its deviation from it is asymptotically normally distributed.
The above implies that if you have two genes in some frequency in the immigrant population, under one way migration that frequency becomes the dominant frequency on the island.
>We investigated various cases of the island model with stochastic migration. If the population is infinite, the immigrants have a fixed gene frequency and the alleles are neutral, the gene frequency on the island converges to that of the immigrants.
What this means is that the genes initially on the model island, in effect, disappeared.

Evolution with Stochastic Fitness and Stochastic Migration
>Migration between local populations plays an important role in evolution - influencing local adaptation, speciation, extinction, and the maintenance of genetic variation.
>A number of studies have shown that when per capita population growth rate is treated as a random variable, rather than a fixed parameter, then directional evolution is influenced not only by the expected fitness of each phenotype, but also by the variance and other moments [23], [28]-[33]. This follows from the fact that, in a closed population, change in mean phenotype is inversely proportional to mean population fitness

<top figure in picture
https://files.catbox.moe/1chmrf.png
Figure 2. The influence of the variance in immigration rates, on the expected change in mean phenotype:
https://files.catbox.moe/6lfnv7.png
Essentially, when the variance in the immigration rate is small it results in a negative phenotypic change on the mean phenotype of a population, as the migrant phenotypes predominate.
Figure 3. The relation between variance in immigration, selection, and in an island-continent model:
https://files.catbox.moe/ubg1ql.png
>The curves show the change in mean phenotypic value assuming a mean phenotypic value as decided by a population's selection.
>The variance in migration is shown in descending value on the curves.
Though the mean rate of migration is the same on all the curves, it is clear that the the island can still get close to fixation of the phenotype favored there, so long as the variance in immigration is high.
So for this figure, assuming that migration is an indefinitely persisting condition, migrants will prevent the local island favored phenotype from remaining intact, as they are essentially working against selection.
_____________________________________
The models/simulations in these studies are based on understanding evolutionary genetics, on how migration influenced evolution, which makes them excellent sources for metaphors on the effects of modern immigration rates in human populations.
Allopatric speciation
Allopatric speciation or geographic speciation is speciation that occurs when biological populations of the same species become vicariant — isolated from each other to an extent that prevents or interferes with genetic interchange. This can be the result of population dispersal leading to emigration, or by geographical changes such as mountain formation, island formation, or large scale human activities (for example agricultural and civil engineering developments). The vicariant populations then undergo genotypic or phenotypic divergence as: (a) they become subjected to different selective pressures, (b) they independently undergo genetic drift, and (c) different mutations arise in the populations’ gene pools.[1]
The separate populations over time may evolve distinctly different characteristics. If the geographical barriers are later removed, members of the two populations may be unable to successfully mate with each other, at which point, the genetically isolated groups have emerged as different species. Allopatric isolation is a key factor in speciation and a common process by which new species arise.[2] Adaptive radiation, as observed by Charles Darwin in Galapagos finches, is a consequence of allopatric speciation among island populations.

https://en.wikipedia.org/wiki/Speciation
Reproductive isolation - Sexual isolation by behavior or conduct
Even where there are minimal morphological differences between species, differences in behavior can be enough to prevent mating. For example, Drosophila melanogaster and D. simulans which are considered twin species due to their morphological similarity, do not mate even if they are kept together in a laboratory.[3][12]Drosophila ananassae and D. pallidosa are twin species from Melanesia. In the wild they rarely produce hybrids, although in the laboratory it is possible to produce fertile offspring. Studies of their sexual behavior show that the males court the females of both species but the females show a marked preference for mating with males of their own species.
https://en.wikipedia.org/wiki/Reproductive_isolation
>Drosophila fruit flies are popular choices for these types of experiments.
https://evolution.berkeley.edu/evolibra ... cle/evo_42
Just imagine what a few extra years of separation could have done for certain human populations…
Well...
>"Human races are evolving away from each other," Harpending says. "Genes are evolving fast in Europe, Asia and Africa, but almost all of these are unique to their continent of origin. We are getting less alike, not merging into a single, mixed humanity." He says that is happening because humans dispersed from Africa to other regions 40,000 years ago, "and there has not been much flow of genes between the regions since then."

Despite their higher socio-economic status and the positive socio-economic gradient in health, third-generation children of second- generation intermarried Hispanic women are more likely to have poor health at birth, even after I account for second-generation health at birth, employ only within-family variations in the extent of assimilation, and consider the endogeneity of intermarriage. These results do not appear to be driven by father's selectivity nor by individual unobservable characteristics associated with intermarriage. The children of intermarried natives do not receive the same "health penalty", nor do Hispanics intermarried to other ethnic groups. The intermarriage "health penalty" largely reflects the higher incidence of risky behaviors (e.g., smoking during pregnancy) among intermarried Hispanic women.

Integration of Ethnic Minorities: Do They Divorce as Natives Do? [Evidence from Denmark]
We investigate the divorce patterns among non-Western immigrants and natives in Denmark. [...] We show that inter-ethnic couples (one native, one immigrant) in general are more likely to divorce than native couples (two natives), while co-ethnic couples (two immigrants) are less likely to divorce, when controlling for differences in socioeconomic characteristics. In particular, co-ethnic couples composed of a first- and second-generation immigrant are less likely to divorce, while the divorce probability is the highest among inter-ethnic couples composed of a native woman and a first-generation immigrant man.

An interesting thing for the U.S. is that many people with parents or grandparents from more than one racial group do not identify themselves as multiracial. So the true population numbers of people who have these illnesses are likely extremely under-represented in census data.
