A or O. If both parents are heterozygous (AO), then the child has a 1/4 chance of being type O. However, if even one parent is homozygous (AA), then the child will only be type A.

Type A or type O.

A child receives a blood type allele from each parent. A is dominant to O, codominant to B

If the parents are both homozygous for type A, their genotype is AA. The child must therefore be Type A as well.

However if both parents are heterozygous for type A, their genotype is AO. A is dominant so their blood is Type A. By a punnent square, their child could have any of the following blood types:

AA- Will be type A.

AO- Will be type A.

OO- Will be type O

Type A only

type a or o

as parents could be AA or AO

presuming they're AO x AO

then theres a 25% chance they'll have a baby with O type blood!

type A only

It could be anything. You can't really know until the child is born. Just because you are both type A does not mean he/she will be.
