Question

The Hardy-Weinberg equation is shown below.

p’+ 2pg + q* = 1
If g is the frequency of the recessive allele, what does g2 represent in the
equation?
A. The frequency of the heterozygous genotype
B. The frequency of the homozygous recessive genotype
O
C. The frequency of the gene in the population
O
D. The frequency of the homozygous dominant genotype

Answer 1

D

Step-by-step explanation:

p2 + 2pq + q2 = 1 and p + q = 1

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homozygous dominant individuals

q2 = percentage of homozygous recessive individuals

2pq = percentage of heterozygous individuals
