Assume that the frequency of gene B in a hypothetical population Is 0.63, that there are only two alleles (B and b) of the gee in the population, that allele B is dominant over allele b, that neither allele has a selective advantage over the other, and that the population is at equilibrium with regard to this particular gene.

The equation p2+ 2pq + q2= 1 representing theHardy-Weinberg proportions examines genes withonly two alleles in a population.a. Derive a similar equation describing the equilibrium proportions of genotypes for a gene withthree alleles. [Hint: Remember that the HardyWeinberg equation can be written as the binomialexpansion (p + q)2.]b. A single gene with three alleles (IA, IB, and i) isresponsible for the ABO blood groups. Individualswith blood type A can be either IA IAor IA i;those with blood type B can be either IB IBor IB i;people with AB blood are IA IB, and type O individuals are ii. Among Armenians, the frequency of IAis0.360, the frequency of IBis 0.104, and the frequencyof i is 0.536. Calculate the frequencies of individuals in this population with the four possible bloodtypes, assuming Hardy-Weinberg equilibrium.In Problems 15–17, you will see that because matingbetween individuals within populations at Hardy-Weinbergequilibrium is random, it is possible to predict…

Taita thrush is an endangered bird endemic to Kenya. Galbusera and colleagues genotyped Taita thrush individuals from three populations at microsatellite markers. You have a museum specimen, and you want to determine which population it most likely to came from. You determine that the museum specimen is homozygous for two microsatellite alleles (A₁ and B₁). The frequencies of each allele in each population are shown in the table below. Population Chawia Mbololo Allele A₁ 0.6471 0.7063 0.6204 Allele B₁ 0.2917 0.1863 0.4000 Ngangao What is the probability that your individual comes from each of the three populations?
