Review the formula for effective population size: N_e (effective population)= .Imagine a total population of 1,000 small rodents.Of these,300 are breeding females,300 are breeding males,and 400 are nonbreeding juveniles.What is the effective population size?

N_e (effective population) is calculated as follows: N = total population size S = sex ratio (males:females) U = percentage of breeding males (out of total males) B = percentage of breeding females (out of total females) e = variance of reproductive success Using the numbers given in the question: N = 1000 S = 1:1 (300 breeding females:300 breeding males) U = 100% (since all males are breeding) B = 50% (since half of the females are breeding) e = not provided in the question, so we have to assume a value (0.8 is a common assumption) Plugging in the values: N_e = 1000 x 1 x 1 x 0.5 x 0.8 x 0.5 = 200 Therefore, the effective population size is 200, which is closest to option C (600)
