1. Population is not used in describing species. Population is a group of organisms of the same species populating a given area, a group of individuals of the same species that live in the same area and interbreed, producing fertile offspring. Interbreeding, sexual reproduction, natural selection and color are used in describing species. Individuals in an interbreeding population share in a common gene pool. My question is can you tell me how interbreeding, sexual reproduction, natural selection and color are...
