*Humans and gorillas both belonged to the biological Family Hominidae and they share more than 97% of their DNA.
*The ABO blood type is the major blood group system that characterizes humans and primates. This has four principal types: A, B, AB, and O.
*So, gorillas, being a primate, most probably have these blood types (A, B, AB, and O).
*It would not be surprising to know that gorillas and humans have the same blood type since they share more than 97% of their DNA.
