In nature, organisms mate without human interference. this is called a) artificial selection. b) selective breeding. c) non-random mating. d) random mating.

D)random mating.

Explanation:

When organisms mate without human interference naturally it is known as random mating. In such mating, each individual of a particular species mates with any of the opposite sex counter part. The individuals of a particular sex are free to choose their mate and in this case each individual of the opposite sex is equal potential partner of opposite sex individual. Such population is known as panmictic population and any sort of recombination is possible in such population because there is no restriction in the selection of mates.
