How many different genes control the blood type of an individule?
4
Does everybody in the same family have the same blood type?
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.
If a father is a plus blood type what type would his children have?
Blood type is a combination of the mother's and the father's genes.
What blood types can be formed by crossing A genes with B genes?
If the parent's blood type is A and B, respectively, the possible blood type of their child are A, AB, B and O.
Is blood type inherited through genes?
Yes
How could parents with blood type A and B have a child with blood type O?
If both parents had heterozygous blood-type genes, then the child could inherit the recessive O type from each parent. Suppose the mother had the genes for A and O, and the father had the genes for B and O. They would then have blood-types A and B respectively. Depending on which parts were passed to the child, any blood type would be possible.
Man blood type B woman blood type AB what would Childs blood type be?
There is no definite answer to this question. It would all depend on which genes the child would get. The child could have more of its moms genes or more of its dads genes or equal! It also has to be known whether the parents have positive or negative blood.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
How could 2 parents with blood type A and B have a child with the blood type of O?
both parents carried the recessive gene for type O blood. the baby then inherited 2 recessive genes and received type O blood. the reason the parents didn't have type O blood is because they carried genes that were more dominant.
Can grandparents blood type effect the blood type of the grandchild?
Yes, genes can be inherited from even great-great-great-great grandparents!
If a mother with blood type A and father with blood type A is there a chance there child's blood type is AB?
100%, but just the fact that your blood type is A, doesn't mean that your genes are AA. If your genes are AO, you would still be type A, because the O gene only expresses itself if both genes are O. So unless you are certain that your blood types are AA and BB, the children could have other types. For example, parents with AO and BO genes could produce children with A, B, AB, or O blood types.
How can someone get their blood type?
You are born with a certain blood type based on genes inherited from your parents and there is no way to influence your type. A simple blood test can inform you what your blood type is and this test can be performed at any doctors office, medical lab or blood donation site.
