It depends some have more of mum or more of dad or both equally
If both parents have blood type O, then the baby's blood type will also be O. Blood type O is recessive, so both parents must have two O alleles to pass on an O blood type to their child.
Yes, it is possible for two parents who are both blood group O to have a child who is blood group A. This can occur if both parents carry the A allele in their genes, even though their own blood types are O.
Yes, so long as they both carry the recessive O.
Yes, but only if both parents carry the O gene since it is a recessive gene.
Yes, if both carry the rH neg factor as a recessive.
If both parents are blood type A, they can each carry a recessive gene for blood type O. When these recessive genes are passed on to the child from both parents, the child will have blood type O. This is a result of both parents being carriers for the O blood type gene.
No, a mother with blood group A Rh negative will not always have babies of the same gender. The gender of a baby is determined by the genetic contribution from both parents, not by the mother's blood type.
No It is only possible for them to have O+ and (if they carry the recessive gene) O-
Anything except type 0. You need an understanding of genetics to answer this. There are lots of good websites that explain it.
It depends on if one or both parents carry type O. If they do not, then the only type will be AB. If they do carry O, then the offspring can be AO, AB, BO or OO.
If both of your parents have Type A blood, the blood of you and your siblings can be A or O.
If both parents have type A blood then the baby should have type A blood. or type O blood
