In Diploid Organisms,the Rate at Which Genetic Variability is Lost

Question

In diploid organisms,the rate at which genetic variability is lost by random genetic drift is
A) 1/2N, where N is the population size.
B) 1/3N, where N is the population size.
C) 1/4N, where N is the population size.
D) 1/5N, where N is the population size.
E) None of these

Accepted Answer

In diploid organisms, the rate at which genetic variability is lost by random genetic drift is 1/2N, where N is the population size. This is because there are two copies of each gene in diploid organisms, and the chance of losing one copy by drift is 1/2N.
