Exam 4: Population Genetics and Natural Selection

Explore all topics

For a population in Hardy-Weinberg equilibrium,in a situation where there are only two alleles at a particular locus,the proportions of genotypes are: SS = 0.64,Ss = 0.32,and ss = 0.04.Calculate the allele frequency for the recessive allele.
