Evolution is one of the unifying themes of biology. Evolution involves change in the frequencies of alleles in a population. For a particular genetic locus in a population, the frequency of the recessive allele (a) is 0.4 and the frequency of the dominant allele (A) is 0.6. (a) What is the frequency of each genotype (AA,Aa,aa) in this population? What is the frequency of the dominant phenotype?

Answer:
Genotype Frequencies:
AA: p2=0.62=0.36
Aa: 2pq=2×0.6×0.4=0.48
aa: q2=0.42=0.16
Dominant Phenotype Frequency:
AA + Aa = 0.36 + 0.48 = 0.84 (84%)
