Does a child have to have the mothers or fathers blood type?

Answer 1

Blood type of a child is determined equally by both parents. Each person has two alleles for their ABO blood type. One allele comes from mom, the other comes from dad. A and B alleles are dominant over the O allele. So blood type O people are two O alleles, one from each parent. Blood type A people can be AA or AO. People with AO are still considered blood type A because A is dominant over O. Blood type B people can be BB or BO. People with BO are considered blood type B because B is dominant over O. Blood type AB people got an A from one parent and a B from another parent. But since A and B are equally dominant, you're AB.

Answer 2

Sometimes, but it is a combined genetic trait the has two genes, one from the mother and one from the father. The gene that is dominant gets expressed as the blood type. Actually, it's more complicated because there are several genes that contribute to blood typing.

Answer 3

No

Blood type is determined by a combination of several genes which determine the types of proteins on the surface of blood cells, principally red blood cells, but also immune system cells, lymphatic system cells, etc.

The genes for blood type are not necessarily adjacent to each other on a chromosome, and a child gets chromosomal material from both parents. Blood typing is a first test, easier and cheaper to do than DNA testing, which can eliminate some parental possibilities. Using the classic A, B, o groups, if the child is AB, and one possible parent is O, that one can be eliminated. An AB child cannot have an O parent.

Answer 5

No, the child can be the fathers or the mothers blood type.

Answer 6

no for mu understanding he can have an other blood type from mother or grand father /mother

Answer 7

It depends... which blood type is domanite. And sometimes two parents with + (positove) blood can give birth to a child with - (negitive) blood type. (Example: Mother: A+ Father: O+ = O-)

Answer 8

No, a child does not have to have the mother's or father's blood type. A child's blood type is determined by the combination of genes inherited from both parents.

Answer 9

yes
