Question
In a certain population, the frequency of three genotypes is as follows:
| Genotypes: | BB | Bb | bb |
| frequency: | 22% | 62% | 16% |
What is the likely frequency of B and b alleles?
Advertisements
Solution
Frequency of B allele = all of BB + ½ of Bb = 22 + 31 = 53%
frequency of b allele = all of bb + ½ of Bb = 16 + 31 = 47%
