a population has 700 individuals, 85 of genotype AA, 320of genotype Aa, and 295 of genotype aa. What are thefrequencies of alleles A and a?
Human ABO blood groups are determined by a single gene with 3 alleles: A, B, and O. In a sample of 300 individuals, 100 are blood type A and genotype AA, 100 are blood type B and genotype BO, and 100 are blood type O and genotype OO. What are the allele frequencies?
There are 350 AA homozygotes, 75 AS heterozygotes, and 40 SS homozygotes in a population. How many A alleles are there? How many S alleles are there? What would their respective frequencies?
