Question

effective population size in a panmictic population of 240 with 200 female ,40 polygamous male?

Answer 1

The correct answer is - 133.3

Effective population size is calculated by using the formula:-

Effective Population (Ne) = 4 x Nm x Nf / Nm + Nf

Nm = the actual number of breeding males and Nf = actual number of breeding females.

In the given question, Nm = 40 and Nf = 200. So, by applying the equation, 

Ne = 4 x 40 x 200 / 40 + 200 = 32000/240 = 133.3

Therefore, the effective population size is 133.3.
