The Afrikaners are an example of a founder effect that occurs when a new colony is started by a few members of the

original population and the random decrease in genetic variation is an example of?

A. Genetic drift

B. Natural Selection

C. Genetic recombination

D. The bottleneck effect

Itvolves the exchange of genetic material either between multiple chromosomes or between different regions of the same chromosome. This process is generally mediated by homology; that is, homologous regions of chromosomes line up in preparation for exchange, and some degree of sequence identity is required.

Explanation:

For further information, one important instance of recombination in diploid eukaryotic organisms is the exchange of genetic information between newly duplicated chromosomes during the process of meiosis.

Answer A. Genetic drift

genetic drift can cause decrease in general pool over the time
