Question

In studying the gene pool of a population, you find that 21% of the population exhibits the recessive trait for eye color and the other 79% of the population exhibits the dominant trait. The dominant allele has complete dominance over the recessive allele. How would you use this information to solve for the frequency of the recessive allele?
Answer


sqrt(0.79)
sqrt(0.21)
0.79^2
1 – sqrt(0.21)

Answer 1

b
hardy weinberq:
P^2+2pq+q^2
q^2 = recessive phenotype
q -recessive genotype
0.79 = 2pq +P^2= dominant phenotype= dominant genotype+heterozygote genotype
