Apopulation of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). brown rabbits have the genotype bb or bb. white rabbits have the genotype bb. the frequency of the bb genotype is.5. w eatry op what is the frequency of the b allele? o.59 what is the frequency of the b allele? o. ll 35 e o. sa

p = frequency of the B allele becomes 0.7

q = frequency of the b allele = 0.3

Explanation:

Hardy Weinberg equation is used to calculate frequencies.

Hardy Weinberg equation can be written as p² + 2pq + q² = 1

Where

p² = frequency of homozygous dominant

p = frequency of B dominant allele

q² = frequency of homozygous recessive

q = frequency of b recessive allele

2pq = frequency of heterozygous dominant

According to given data

p² = frequency of homozygous dominant = 0.5

p becomes √0.5

p = frequency of the B allele becomes 0.7

Sum of both frequencies = 100% = p + q = 1

so q = 1 - p

q = 1 - 0.7

q = frequency of the b allele = 0.3
