Can siblings have different blood types with the same parents?

Can siblings have different blood types with the same parents?

Yes, two siblings from the same parents can have different blood groups from their parents. This is because the four ABO blood groups, A, B, AB and O, arise from a child inheriting any one of each blood group gene forms (or alleles) A, B or O from each biological parent.

Is it possible for a child to have different blood type from parents?

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.

Can two O positive parents have a child with a different blood type?

Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.

Can parents with A and B blood type have an O baby?

Someone who has an A and a B version of the blood type gene makes both A and B proteins. And so is AB blood type. But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids.

What is it called when mom and baby have different blood types?

Rh disease occurs during pregnancy. It happens when the Rh factors in the mom’s and baby’s blood don’t match. It may also happen if the mom and baby have different blood types.

Are siblings expected to be of same blood group?

As far as this discussion is concerned, the answer is no. Siblings may not have the same blood group. This results in various circumstances such as if both the parents are of type A (for instance), the the offspring will have a type of either A or AB. So, one of the siblings may have a blood type of A and the other with type AB. I hope you got it.

Can paternal twins have different blood types?

Monozygotic (identical) twins will have the same blood type. (Except in very rare exceptions.) Dizygotic (fraternal) twins may have the same blood type, or they may have different types.

Can full sisters have different blood types?

They can yes BUT it all depends upon what the parents blood groups are and also whether they are pure for their groups. So sometimes the children have to be all the same but in other siblings there can be several differences. One parent with A+, the other with A-, can they produce child with O blood group.

How can child have different blood type than both parents?

Yes to both: If both parents are B+, any of their children can be either B+ or O+. Blood type is determined by the presence of either an A or B antigen, regardless of amount., with inheritance from both parents.
