In a certain population, the frequency of three genotypes is as follows:

Genotype BB Bb bb
Frequency 22% 62% 16%

What is the likely frequency of B and b alleles?

Answers (1)

Formula:
Frequency of allele B= frequency of BB + 12 of Bb
Frequency of allele b= frequency of bb + 12 of Bb
Given data:
Frequency of BB= 22,Frequency of Bb= 62,Frequency of bb= 16
Sol:
Frequency of allele B=22+(12)×62=53%
Frequency of allele b=16+(12)×62=47%
Answer:
Frequency of allele B=53%
Frequency of allele b=47%
