There is no disease caused by parents having the same ABO blood group.
A or AB
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
can a mother of o blood group have a healthy child with a father type o
O
ab
95% not.
Yes, it is possible for a mother with blood group O and a father with blood group AB to have a child with blood group O. This would occur if the child inherited the O allele from the mother and the O allele from the father.
No
The mother and father both have heterozygous alleles for the blood group A. The blood group A can have the alleles AA or AO, when both parents are AO, there is a one in four chance that the child will have blood group O as this blood group is recessive.
Probably more than likely A+. Because the +Rh gene is usually dominate. Take for instance- Mother is A+, Child is A=. Father is A=, In this instance the father has the dominate gene for the absence of the Rh antigen on the redcell. The mother is recessive.
yeah its possible.
The child could either be blood type A or blood type B.
