Such as Chimps is 90% genetically similar to human, but they not identical in physical appearance.
So, at present, scientists use genetic similarities between species to help classify them as related species, rather than focusing on physical or structure of any species.
This change in chromosome number is the result of B. Fertilization. Both of the individual gametes from the male and female combine together to produce a zygote or developing offspring that is diploid in most cases, and possess both sets of genetic content or chromosomal information, one from each parent.
C, because it makes the most sense hoped this helped !!!!!
