You are studying forget-me-nots and you discover that there are two flower colors (blue and white) that follow Mendelian inheritance patterns. Breeding data suggest that the blue allele is dominant to the white allele, and when you examine 200 flowers from your wild population you find 32 plants with white flowers. Based on this, what would you expect to be the frequency of the blue allele? 13% 36% 50% 60%

Solution

Answer: 60%

Explanation:

Blue genotype= BB or Bb

White genotype= bb

The frequency of white flower = q^2= 32/200 = 0.16

The frequency of white allele = q = 0.4

p + q= 1

p = 1-q= 1-0.4= 0.6

Therefore the dominant, blue allele frequency= 0.6 = 60%
