b and o
Yes, an O positive parent and an M positive parent can have an AB negative child if both parents are carriers of the A and B genes and the child inherits one A and one B gene from each parent. This combination would result in the child having blood type AB.
The child could have either blood group A or B, but not AB or O. Each parent contributes one blood type allele, so the child could inherit an A allele from one parent and a B allele from the other, resulting in blood group AB. Alternatively, the child could inherit an A allele from one parent and an O allele from the other, resulting in blood group A, or a B allele from one parent and an O allele from the other, resulting in blood group B.
No, the blood types a and b are dominant alleles and would mask the recessive o blood type.
b posgative
The other parent would have to have blood type O to have a child with that blood type.
Colorblindness is not determined by blood type. Everyone has two alleles for blood type: A, B, or O. If one parent is AO and the other is BO, the child can be AB, AO, BO, or OO.
At least one parent would have to have an RH Positive blood type. Beyond that you can not tell. Because the O trait is a recessive trait, either parent could have A or B or O blood, since, for example, a parent with A blood could have one A gene and one O gene that together would express the A trait. That parent's child could inherit either the A gene or the O gene. The other parent could have B based upon one B gene and one O gene that together would express the B trait. That other parent's child could inherit either the B gene or the O gene. Only if the child of both parents inherited an O gene from each parent, would the child have O blood. As to the RH factor, it is a dominant trait, so that if the child has the trait expressed, it would have to have been in one of the two parents. Hope this helps.
Yes, it is possible for two parents, one with AB+ blood type and the other with O+ blood type, to have a child with O+ blood type. When two parents with different blood types have a child, the child's blood type can be a combination of the parents' blood types through genetic inheritance.
Yes, it is possible for parents with blood types O and AB to have a child with blood type O. The child would inherit an O allele from one parent and an O allele from the other parent, resulting in blood type O.
The possible blood types of the child would be B and O. Each parent can pass on a B allele or an O allele, resulting in a 50% chance of the child inheriting a B allele from each parent, making them blood type B. If the child inherits an O allele from one parent and a B allele from the other, they would be blood type B.
No, At least one parent would have to be an A (or an AB) for a child to have group A blood.
If the parents are AO+ and BO-, they can create a O+ child: both parents contribute O and the AO+ parent contributes + (the child's genetic makeup would be OO+-). If the parents are AO+ and BB-, they could not create an O+ child as the BB- parent would contribute a B (possible combinations would be AB or BO in that case).
