The inbreeding effective population size is often lower than the census size of a population because of
A)inbreeding depression.
B)fluctuating population size.
C)uneven sex ratios.
D)B and C
E)All of the above

Quizplus · Accepted Answer

Inbreeding depression can reduce the effective population size by decreasing the survival and reproductive fitness of individuals. Fluctuating population size can also reduce effective population size because it increases the chance of genetic drift and loss of genetic diversity. Uneven sex ratios can limit the number of potential mates and decrease genetic diversity, further lowering the effective population size. Therefore, both B (fluctuating population size) and C (uneven sex ratios) are factors that can reduce the inbreeding effective population size.
