Which factor listed below most likely results in the loss of genetic variation from small populations?
a: mutation
b: genetic recombination
c: genetic drift
d: migration

Loss of genetic variation from small populations results to Genetic drift

The statement that best sums up evolution is the change in a population through genetic variation over time. Natural selection may be through (1) differential reproduction, that is, not all organisms are able to reproduce to their fullest capacity because nature cannot simply sustain it and (2) acquire genes, that is heredity.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
