Yes. The father's phenotype is AO+*; the mother's is OO--.
Yes, if both the mother and the father are carriers of the recessive Rh negative trait, they can produce a child with O negative blood type. The child would inherit one Rh negative allele from each parent, resulting in a negative blood type.
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
It would all depend on the Dominant and Recessive blood type genes in the mother and father it is near improbable to tell unless you take a blood sample to test the blood type. == A rhesus negative mother and positive father can produce either a rhesus negative or positive child. A type A and type O parental combination will only produce either type A or type O children. So an A- mother and O+ father will normally produce offspring having the possible blood groups of A+ or A- or O+ or O-. See the link for a full explanation.
The father's blood type could be either A positive or A negative. The children inherited the A antigen from the father, resulting in their blood type as A negative. The Rh factor (positive or negative) is inherited separately, so the father could be either positive or negative.
for sure
Yes.
Yes. The father's phenotype is AO+*; the mother's is OO--.
Yes
Yes.
the baby may be A 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.
yes if both are heterozygotes
# yes, if father is + - for RH and mother - - (negative) or + - (positive); the father can generate sons A, B, or AB depending by mother's group.
It's called "positive" and "negative" - yes the "A" father and "B" mother can each give a gene to produce "AB"; The Rhesus gene is either positive or negative so the baby could get either.
