Question

Which of the following occurs when the evolutionary effects of genetic drift is the greatest?

The population size is small
The population size is large
$exual selection occurs
Intraspecific competition is weak

Answer 1

The population size is small.

Step-by-step explanation:

Answer 2

The population size is small

Step-by-step explanation:

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
