Question

A population 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?

Answer 1

idk what its called but this is when a grey cat is a recessive allele so it doesnt appear in the first generation, but later on more and more grey cats start showing up

Answer 2

either that or it may be a mutation

Answer 3

i think its like gene flow and gene drift
