Could two parents have a child with Type O blood and a child with Type A blood?

Answer 1

oh yeah
Misread

okay it goes like this

The child with type O blood is genotype OO
The child with type A blood is genotype AA or AO

So if one parent is genotype AO (and it doesn't matter what genotype the other parent is so long as they contribute an O... hence OO AO or BO) they can have a child with OO (blood group O) and a child with AO (blood group A)

Answer 2

Although the other answers, are correct, there is a better way of representing the alleles of the ABO blood group. The four blood groups result from various combinations of three different alleles for the enzyme (I) that attaches the A or B carbohydrate to red blood cells. The enzyme encoded by the I^A allele adds the A carbohydrate, whereas the enzyme encoded by I^B adds the B carbohydrate (the superscript indicates the carbohydrate). The enzyme encoded by the i allele adds neither A nor B. Because each person carries two alleles, six genotypes are possible, resulting in four phenotypes. Both the I^A and I^B alleles are dominant to the i allele. Thus, I^A I^A and I^A i individuals have type A blood, and I^B I^B and I^B i individuals have type B blood. Recessive homozygotes, ii, have tope O blood, because their red blood cells carry neither the A nor the B carbohydrate. The I^A and I^B alleles are codominant; both are expressed in the phenotype of I^A I^B heterozygotes, who have type AB blood.

So, it is possible if to have a children with type A blood and another with type O blood as long as you satisfy two requirements:

1: both parents carry the recessive allele i.
2: at least one parent must carry the I^A i gamete.

Answer 3

Yes. As long as they both carry an allele for A and O blood types.

The pundit square for their possible children (AO x AO) would look like this:
__A___O___
A| AA AO
O|AO OO

So they are 75% likely to have a child with A type blood (A is dominant over O), and 25% likely to have a child with O type.

Answer 4

Blood group inheritance

Father
Mother/ O A B AB
O O O, A O, B A, B
A O, A O, A O, A, B,AB A, B, AB
B O, B O, A, B, AB O, B A, B, AB
AB A, B A, B, AB A, B, AB A, B, AB

Answer 5

yeah if one parent was type O and the other parent type A.

Answer 6

Yup. I'm O my sis is B and my bro is A. Parents are O and AB respectively.
