If both parents are O ,,,,,,,,,,,, all kids will be O ,, no possibility for A
possibility of b or o not ab
Normocytic and normochromic blood is normal.
No, it is not possible for the baby to have an A group with both parents being O. This is because the parents would have the genotype OO,thus on recombination, the only possible outcome is again an O.
No, Parents of a type b child would have to be either AB, BB, BO or OO.
Pregnancy tests bought from a pharmacy can tell you approximately 2-3 weeks after conceiving. A blood test at the doctor can tell you within a week of conceiving.
*Note from asker: Both my parents and at least one brother have B pos blood... Possibility of a throwback gene?
One cannot predict the blood type of the offspring unless the blood types of both parents are known. Blood group O is not common is a population. There is a possibility of this allele being repressed in the presence of a more dominant blood group allele. Once the blood groups of both parents are known, one an look at all the possibilities that the offspring can have and make an accurate prediction.
If you mean blood types, yes. If both parents carry the recessive "O" blood gene there is a 1 in 4 chance each child could be type O. If you can find out the blood types of the parents' parents and even the grand parents you can narrow it down (sometimes). If you can eliminate the possibility that the "father" carries a recessive "O" he would be eliminated as a possible parent.
No. If both parents have a negative blood type, the child will either have the mother's blood type,or father's blood type, or if one parent is A- and the other B- only then can a child be born AB-. However, if two people with negative blood types try to have a baby, that may be very difficult. Sterility usually runs on the negative blood types, but conceiving a child is not impossible for them.
Its a possibility. Although the parents have to both be heterozygous with the type O blood. Because type O blood is recessive while type A and type B are dominant.
