Best Answer

Not everyone in the same family has the same blood type. There are two separate genes that determine the blood type a person will have. One is for type such as O, A, AB, or B. The other determines if the blood will be positive or negative. It depends on which genes a person is born with. Both genes are on different chromosomes.
