Question

A population of 500 jackrabbits has two alleles, Fᴮand Fᵂ, for a locus that codes for fur color. FᴮFᴮ individuals have black fur, FᴮFᵂ individuals have gray fur,FᵂFᵂ individuals have white fur. 250 individuals are black, 150 individuals are gray and 100 individuals are white. What are the observed genotype frequencies in this population?

a. 0.71, 0.50, 0.45
b. 0.42, 0.46, 0.12
c. p², 2pq, q²
d. 0.50, 0.30, 0.20
e. 0.65, 0.35

Answer 1

The observed genotype frequencies in a population of 500 jackrabbits with different fur colors are 0.50 for FᴫFᴫ (black fur), 0.30 for FᴫFᴬ (gray fur), and 0.20 for FᴬFᴬ (white fur). The correct answer is d. 0.50, 0.30, 0.20.

Step-by-step explanation:

The question pertains to calculating genotype frequencies in a population of jackrabbits for a specific locus concerning fur color. Having a population of 500 jackrabbits with 250 black (FᴫFᴫ), 150 gray (FᴫFᴬ), and 100 white (FᴬFᴬ) individuals, we can calculate the genotype frequencies using these numbers.

To find the genotype frequency, we divide the number of individuals with a particular genotype by the total population:

FᴫFᴫ frequency: 250/500 = 0.50

FᴫFᴬ frequency: 150/500 = 0.30

FᴬFᴬ frequency: 100/500 = 0.20

Therefore, the observed genotype frequencies in the population are:

FᴫFᴫ frequency: 0.50

FᴫFᴬ frequency: 0.30

FᴬFᴬ frequency: 0.20

The correct option is d. 0.50, 0.30, 0.20, which corresponds to the frequencies of the black, gray, and white fur genotypes, respectively.
