Consider a collection of 50 distinct alleles,each at equal frequency in a population.The time before the first coalescent event will be shortest if
A)Ne = 100
B)Ne = 100,000,000
C)Ne = 100,000
D)Ne = 1,000,000,000.

Question

Quizplus · Accepted Answer

The time before the first coalescent event is determined by the effective population size (Ne) of the population. The smaller the Ne, the shorter the time before coalescence. Therefore, choice A) Ne = 100, with a relatively small Ne, would result in the shortest time before the first coalescent event. Choices B), C), and D) with much larger Ne values would result in longer times before coalescence.
