New mutations -- or changes in the DNA -- are theoretically one way these kinds of uncommon scenarios can happen.


Can O and A have a baby?

Blood type is based on genes from each parent. So if one parent is type O and one is type A, the baby will likely be type A. 6 The reason the baby wouldn't have type O blood is because the gene for O is recessive (meaning it's only expressed if the baby gets it from both parents).

Do babies always have the father's blood type?

No it doesn't. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent's blood type.

Can 2 O parents have an A baby?

Two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types.
