Question

The color distribution for a specific population of snakes is 150 red, 60 orange, and 40 yellow. The allele for the color red is represented by RR, whereas the allele for the color yellow is represented by RY. Both alleles demonstrate incomplete dominance. Use the information to answer the following questions. Calculate to at least two decimal places. What are the genotype frequencies in the population?

Answer 1

Answer:

Frequency of genotype RR

$0.6$

Frequency of genotype RY

$0.24$

Frequency of genotype YY

$0.16$

Explanation:

Total number of species

$150+60+40\\= 250$

Genetic frequencies of the snake population is equal to number of species of a given genotype divided by total number of species.

Thus,

Frequency of RR

$= \frac{150}{250}\\ = 0.6$

Frequency of RY

$= \frac{60}{250}\\ = 0.24$

Frequency of YY

$= \frac{40}{250}\\ = 0.16$
