Question

There are multiple types of non-random mating. Which of the following correctly describes the effects of non-random mating on genotype frequencies? a. Inbreeding leads to an excess of heterozygotes, and outcrossing (negative assortative mating) leads to an excess of homozygotes. b. Both inbreeding leads and outcrossing (negative assortative mating) lead to an excess of heterozygotes. c. Inbreeding leads to an excess of homozygotes, and outcrossing (negative assortative mating) leads to an excess of heterozygotes. d. Both inbreeding leads and outcrossing (negative assortative mating) lead to an excess of homozygotes.

Explanation / Answer

Option C is the correct answer. As inbreeding tends to keep old genes together thus enhances the chances of production of homozygotes.

Outcrossing leads to putting together of new genes rapidly which results in formation of excess of heterozygotes.
