is it possible to for a child to inherit its a+ blood type from its grandparent if both parents are 0&AO type?

Answer 1

No. Bloodtypes are the only gene that come strictly from the parents. Both sperm and egg carry the trait for the blood type of the individual only. Blood type can only come from mom or dad.


*For those who want to give me a thumbs down.. the question was could the child inherit its blood type from its GRANDPARENTS. There is no A parent, and the child is not AO
Read the question. Im the only one who answered it right

Answer 2

If one parent is O and the other is AO, then the child could also be AO

A and B are codominant, and O is recessive. So a person with type A blood could be AA or AO. Type be could be BB or BO. If one parent passes an A and the other a B, the child would be AB. If both parents pass an O, the child is O.

So in this family with O and AO parents, statistically half the kids would be AO and half the kids O.

Answer 3

he probably got it form the parent that is "OA" or A type.
each parent gives one blood type gene-- the A's have A proteins on them and the O has "no" proteins on them (not really an O protein)if a parent is O then he donates a "no" protein gene to the child's blood type, and the A O parent donates either a "no protein" gene ("O") or an "A" protein gene (A) if the "A" protein gene is donated and the other parent gives the "O" gene ("no protein") then the child will have an A blood group type. (if he/she donated the O, the baby would have "no protein" or O type.

The (+) represents the "rH factor protein gene-- if it is (+) there is a rh factor, if it is (-) no rh factor, so I think somebody must have an RH (+) factor gene in their blood genes-

genetics very complicated but hope it explains it-- so basically, from a parent, not a grnadparent- some parent has an A(+) protein genes to give the baby

Answer 4

No. Allele for blood crew O is recessive, you'll choose 2 copies to be blood crew O. when you consider that neither be certain ought to have an allele for blood crew A, the youngster can in problem-free words inherit O alleles, and be blood crew O.
