Detailed explanation-1: -Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.
Detailed explanation-2: -Selective breeding, also known as artificial selection, is a process used by humans to develop new organisms with desirable characteristics. In selective breeding, a breeder chooses two parents with beneficial phenotypic traits to reproduce, yielding offspring with those desired traits.
Detailed explanation-3: -The purpose of selective breeding is to develop livestock whose desirable traits have strong heritable components and can therefore be propagated.
Detailed explanation-4: -Although selective breeding can increase the prevalence of desirable traits by increasing the frequency of favorable genes within the gene pool, undesirable traits, which can cause hereditary health problems, can also increase as a consequence of inbreeding.
