many populations throughout central eurasia share high frequencies of the b allele. what does this pattern suggest about the evolutionary history of these populations? describe the evolutionary force that probably caused this trait distribution. view keyboard shortcuts edit view insert format tools table 12pt paragraph

Many populations in central Eurasia have high B allele frequencies; this pattern suggests or supports evidence of local adaptation in Eurasian human populations.What is the evolutionary force?Alleles are gene variants that code for different traits in an organism. Mutations or evolutionary adaptations could be to blame. The presence of the O allele is common in Americans.The American evolutionary patterns suggest that:A, B, and O alleles code for human blood type. The individual inherits two alleles from his or her father and mother.The frequency of the O allele in the allele in Americans is higher, reaching 100% in some cases.The evolutionary pattern suggests that these populations are descended from the O-blood type population. The phenomenon is frequently explained as a result of the founder effect, which causes the loss of genetic variation.To learn more about evolutionary force refer to :https://brainly.com/question/14256554#SPJ4
