MY BLOOD TYPE AND ANCESTRY
|
|
|
| Where did I get my Blood Type? |
| Your blood type is a result of the intermingling of your parents blood type and their parents blood type and so on and so on.
Our blood types were determined at the moment of conception. There are basically four primary common blood types.
The most common is blood type O, followed by type A, type B, and the least common is blood type AB. |
|
|
|
| How was my Blood Type determined? |
| Blood type is determined by the alleles that we inherit from our parents. Alleles are genes controlling the outcome of our blood type. There are three common blood type alleles: A, B, and O. We all have two alleles, one inherited from each parent.
Blood types A and B are dominant alleles. When present, A and B have greater control over the outcome of the blood type of a child. Blood type O is recessive, generally both parents have to be O for the child to be O. |

|
The possible combinations are:
OO = Blood type O
AO = Blood Type A
BO = Blood Type B
AB = Blood Type AB
AA = Blood Type A
BB = Blood Type B

Regarding
paternity, DNA testing is more reliable and has the final word in
legal cases. |
|
|
|
| A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father). |
