Question

one consequence of genetic drift is______.
A. new genetic variation
B. positive selection
C. loss of genetic variation
D. population growth

Answer 1

The correct answer is the loss of genetic variation. This is because after genetic drift, the original poulation of a species decreases in number, and the new dominant genes in the population will live up to reproductive age, and increase the newer genes will thrive.

Answer 2

C. Loss of genetic variation.
Genetic drift is a random fluctuation between genetic difference. With genetic variation, there might be a very low genetic difference which cause a loss of genetic variation.
