Answer 1

The effective population size for a population with 50 males and 100 females, assuming random mating and no selection, mutation, or migration, is 133 when rounded to the nearest whole number.

Step-by-step explanation:

The effective population size (Ne) is a concept in population genetics that reflects the genetic diversity of a population. For a population with different numbers of males and females, the effective population size can be estimated using the formula: Ne = (4 * Nm * Nf) / (Nm + Nf), where Nm is the number of males and Nf is the number of females.

In this case, with 50 males and 100 females, we can calculate the effective population size as follows: Ne = (4 * 50 * 100) / (50 + 100) = (20000) / (150) = 133.33. Rounding to the nearest whole number, we get an effective population size of 133.
