Can you have O blood if your parents are A and B?

Can you have O blood if your parents are A and B?

To be O, you usually need to get an O from both mom and dad. But an AB parent usually has an A and a B version, not an O. So they usually can’t have an O child.

Can two parents who have blood type A have a child together with blood type O How do you know?

Even though both parents still have blood type A, Dad can pass on either his A or his O gene version. Mom can also either pass on her A or her O. Because of this, you can see that there’s 1 in 4 or 25\% chance for a child to have OO, or blood type O.

What is the probability that the couple will have a child with blood type O?

If the father is heterozygous, there is a 50\% probability for a blood type A child and a 50\% probability for a blood type O child.

Can an O blood type have an AB child?

An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.

Can an O+ have an A+ Child?

When we get rid of the extra one, we have this, easier to manage table: As you can see, only one out of the eight boxes is OO -/-. That means each child of these parents has a 1 in 8 chance to have a baby with an O- blood type. An A+ parent and an O+ parent can definitely have an O- child.

Can a parent that has type O blood and a parent that has type A blood ever have a child with type B blood?

Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter….How are ABO alleles inherited by our children?

Inherited	Blood type of child
O from the mother A from the father	A
O from the mother B from the father	B

Is blood type O homozygous?

There are six possible genotypes (genetic makeup of inherited alleles) and four phenotypes (expressed physical trait) for human ABO blood types. The A and B alleles are dominant to the O allele. When both inherited alleles are O, the genotype is homozygous recessive and the blood type is O.

Can AB and O+ have babies?

In most cases, an O parent and an AB parent will have only A or B kids. It is only very rarely that they might have an AB or an O child (see the links at the end for these exceptions). Isn’t genetics fun! What I’ll do for the rest of this answer is go through why an O parent and an AB parent will have only A or B kids.

What blood types make an AB baby?

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).

Which parent determines the blood type of the child?

Each biological parent donates one of their two ABO alleles to their child. 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.

What is normal BP for a 9 year old?

For diastolic, there are 57 to 79. Blood pressure is measured in millimeters of mercury. Systolic level in normal blood pressure for 9 year old is quite similar to adult. Children have stable blood pressure than baby due to organs work properly. For adults, 90 to 120 are the normal level for systolic.

What is the normal blood pressure for a 10 year old?

The normal blood pressure for a 10 year old boy is 130/90.

How does inheritance of blood types work?

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.
