Can a child have a different blood type than the father?

Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.

Are you always your father’s blood type?

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Could a man with an O blood type be the father of a child with type AB blood?

In cases of questioned paternity, ABO blood-typing can be used to exclude a man from being a child’s father. For example, a man who has type AB blood could not father a child with type O blood, because he would pass on either the A or the B allele to all of his offspring.

Can paternity be determined by blood type?

Unfortunately, you cannot determine paternity by using the blood type method alone. Each person inherits ABO Blood Type from their parents. For Example, If a mother is O blood type and both of the alleged fathers are A blood type and the child has an A blood type.

Can a child be born with both parents’ blood types?

No. The child’s blood type is decided by genes that come from both parents. The mother contributes one gene, the father contributes one gene. If the father is O and the mother is A or B, the child will be A or B like the mother, because the father’s O is recessive. If…

Can a man with B or O blood have fathered this child?

The letters listed in that cell are the possible ABO groups of the father. For example, if the child is A and the mother is O, the father MUST be A or AB. It is biologically impossible for a man with B or O blood to have fathered this child.

Can blood type confirm paternity?

Last, blood types can not confirm paternity. The kid’s blood type may match the father’s (or be a possible combination of the parents’), but that doesn’t mean that he really is the father. It’s all basic ABO info and is in your med-surg text.

Why does a father and son have different blood groups?

You can be an A (dominant) and still have an “O” gene (recessive) on the other DNA Strand (You have two). So your son doesn’t have to be your blood type … he could be an O. Originally Answered: Why does a father and son have different blood groups? Blood Group (A, B, AB, O) inheritance depends on both parents’ Blood Groups.
