Answer:
q = 0.2, p = 0.8
Explanation:
According to Hardy-Weinberg equilibrium,
p + q = 1
pΒ² + 2pq + qΒ² = 1 where,
p = frequency of dominant allele
q = frequency of recessive allele
pΒ² = frequency of homozygous dominant genotype
2pq = frequency of heterozygous genotype
qΒ² = frequency of homozygous recessive genotype
Here,
qΒ² = aa = 0.04
q = β0.04 = 0.2
p = 1 - q
= 1 - 0.2
= 0.8
