One consequence of genetic drift
a. new genetic variation
b. positive selection
c. loss of genetic variation
d. population growth

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.

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.

Hope this helps:)
