if one parent is a+ and the other is o+,will the offspring be either a or o positive?or ao=? or?

Answer 1

The parent who is O+ has one of the following genotypes:
O/O +/+ (rh factor inherits separately)
O/O +/-

The one who is A+ is one of the following (and you can't tell which):
A/A +/+
A/A +/-
A/O +/+
A/O +/-

so the kids will be either A+, A-, O+, or O-.

Answer 2

Type doesn't influence RHesus factor - the negative RH seems to be recessive, so both parents would contribute to that - and both can be non-expressive, that is, have positive RH but both carry the negative which combine to express in the child.
Types are basically a clean slate (O), a touch of white chalk (A), a touch of yellow chalk (B), or some of both (AB). These (or lack thereof with O) - and RH factor - are proteins on the surface of red corpuscles (blood cells) similar to antigens, so mixing blood types causes allergic reactions.
The O parent has no A or B trait, while the A parent has A but can pass the blank side (when the double DNA strand splits) that combines to form O - passing the A side would seem to create type A in the child, but I'm not sure if it would have to be dominant. It would seem there would be more A and B types if just one parent's contribution were required for expression. Having AB expresses as having each attached protein on the cell, coming (if I remember) each - A and B - from each parent. This hardly makes a case for the types being recessive. But in summary, if one parent had the B trait, would express (not in this case) so neither carries B. The O parent has no A, but the A parent can have an O child. The RHesus seems to be a more-familiar recessive trait (the negative, that is), so the child could be A or O and be + or - RH. Ruled out are AB and B. Hence, A+,A-, O+, or O-

Additionally, mixing RH in transfusion is almost always bad. AB has both proteins, so only AB recipients can tolerate it. A or B recipients can't tolerate the opposite type or AB because it has the opposite type. O recipients can't tolerate either one - A, B, or AB. O blood has neither protein on its red corpuscles, so it can be tolerated by any type recipient (assuming compatible RH). So O is called universal donor and AB is called universal recipient.

Answer 3

Blood type comes from the father of the child, so whatever the father is, the child will be. The most common problem with the Rh factor is if the mother has, for example, O negative blood and the father is O positive. If the mother is exposed to O postive blood by one way or another, antibodies will be produced that can cause problems during pregnancy for the unborn child, up to and including possible death for the child if there are complications.

Answer 4

The child could be A+, O+, or carry both A and O factors; in each case, the positive rh factor will be present, as that is all either parent has to "donate."

Answer 5

there is no such thing like AO. Either the child be A or O.

Answer 6

I am an MD. The possible blood types in children from such a union are A+, A-, O+, O-

Answer 7

my mom is 0 and my dad is AB positive...I'm RH negative because of my moms 0 type Im told.
