It depends. If the mother is heterozygous rh+ rh- for the rh blood type, then the baby could inherit an rh- allele from both parents, and then it would be rh negative.

What is the expected phenotypic ratio among children born to a mother having the genotype IAiO and a father with the phenotype AB?

The mother has blood type A (IA) and is a carrier of the recessive O (iO) allele. The father is blood type AB, meaning he has both A and B alleles. Their children would have a 50% chance of inheriting the A allele from the mother and a 50% chance of inheriting the B allele from the father, resulting in a phenotypic ratio of 100% AB.


Why can the blood group of a mother and her baby not be the same after birth?

The blood group of a mother and her baby can be different because each person inherits their blood type from both parents. The baby's blood type can be a combination of the mother's and father's blood types, allowing for different blood groups between mother and baby.


Can a mother with a negative blood and father with o positive blood have b positive blood group baby?

Yes, it is possible for a mother with O negative blood and a father with O positive blood to have a B positive blood group baby. The child would inherit one gene from each parent, leading to a combination that could result in a B positive blood type.


if a mother blood type o+ the father blood type is b+ the child is a+ can he be father that child?

Yes, the father with blood type B+ could be the biological father of a child with blood type A+. A child can inherit a different blood type from their parents due to genetic inheritance involving multiple alleles for the ABO blood group system.


What blood type will the offspring be if the Mother has A- blood and the father has O- blood?

The offspring could have blood type A- or O- due to the possible combination of A and O alleles from the parents.

A or AB


Could a father with a blood group ab have a child that is O blood group?

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.

No


Can a mother with blood group O and gather blood group AB produce O blood group child?

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.


How does a A blood type mother AND a father have a -0 blood type child?

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.


If mother is A negative blood group and the child is A positive blood group what is the father's likely blood group?

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.


If a mother is B positive blood group and a father is O negative blood group can they have a child that is O positive blood group?

yeah its possible.


What blood group will the baby have if mother is o and father is blood group ab?

The child could either be blood type A or blood type B.
