No. AB parents cannot have O type children; however, A, B, and O can have O type children. If the father is AB and the mother is A the child will have to be either A, B or AB.
Yes.
Yes. If the mother is OO and the father is OB then yes. If the mother is OO and the father is BB then no.
Father can be A, B, or O.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
B or O
Father and mother ( B and O) the father alleles here are heterozygous (IBi) IBi ... ii children are : IBi , IBi , ii , ii so 50% of children may be type B & 50% of children may be type O but if the father B type is homozygous ( IBIB) 100% of children will be type B ,,, (IBi) if father is (Rh+Rh+) and mother (Rh-Rh-) all kids will be Positive. but if father (Rh+Rh-) and mother (Rh-Rh-) 50% of children will be + 50% of children will be -. Medical Answers need to be confirmed and re-confirmed.
NO , mother can be AO , AA ........... father OO onlydaughter .. A or O never B
Theoretically : If mother AB+ ( with hetero alleles Rh+Rh-) children are : A+,A-,B+,B- If mother AB+ ( with homo alleles Rh+Rh+) children are : 100% A+,B+
An AB+ and B- couple can't have a child with blood type O. They can have children with blood types A, B, or AB, and can have children with Rh negative or Rh positive blood.
The children can be A positive or B positive but not O or AB.
