10. 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?

Solution:

Frequency of B allele = all of BB + 1/2 of Bb = 22 + 31 = 53%

Frequency of b allele = all of bb + 1/2 of Bb = 16 + 31 = 47%
