Question

The color distribution for a specific population of lizards is 170 blue, 50 turquoise, and 30 green. a. The allele for the color blue is represented by BB, b. whereas the allele for the color green is represented by BG. c. Both alleles demonstrate incomplete dominance. What are the genotype frequencies in the population

Answer 1

Answer:

Frequency of BBBB genotype = 0.68

Frequency of BBBG genotype = 0.2

Frequency of BGBG genotype = 0.12

Explanation:

Genotype frequency = number of individuals of that genotype/ total number of individuals

In this population three types of individuals are present: blue, turquoise and green.

Frequency of BBBB genotype (blue) = 170/ ( 170 + 50 + 30)

= 170/250

= 0.68

Frequency of BBBG genotype (turquoise) = 50/250

= 0.2

Frequency of BGBG genotype (green) = 30/250

= 0.12
