Apopulation of black cats has been interbreeding. however, in one litter, a sole gray kitten is born. the successive generations now have a few gray cats. which mechanism is responsible for introducing this new allele in the cat population?

gene selection

gene mutation

gene flow

genetic drift

Option A, Gene Selection

Explanation:

Gene selection is a process by which some specific trait with in an organism become more extensive than other traits. As in the given case , grey color cats are being produced more frequently in the coming generation even when two black cat species interbreed. This means somewhere the two black cats have some other color allele (not expressed earlier)  which expresses itself more extensively in the later generation.

Hence , option A is the correct answer
