Could father with a blood group and mother with b blood group have child with o blood group?

Answer 1

The most likely blood type for the child will be A+.

However, it will depend on whether the father is heterozygous (Ao) or homozygous (AA).

If the father is heterozygous for both traits (Ao and +-) the possibilities are:

A+, A-, O+ and O-.

If the father is homozygous for both (AA and ++) then the child must have type A+.

Answer 2

If the mother's blood group is A, that means she has a gene for A but not the gene for B. I believe that means that her genotype is either AA or AO. Since the father's blood group is O, he has neither the A gene nor the B gene, so his genotype is OO.

The child gets one gene from each parent. The gene from the father will always be O, since he is OO, while the gene from the mother could be either A or O. Therefore, the child's possible genotypes are AO and OO, meaning her blood group is either A or O.

Answer 3

Either A or O. Depends on mom's genes. Everyone carries two alleles for blood type--one from each parent. The O type is recessive--you need two O alleles to display the O type. Because dad is O, we know he's got two O alleles. Mom is carrying a dominant allele, of which for blood type there are two varieties, the A and the B. If you have one or two A alleles you're A type, if you have one or two B alleles you're B type and if you have one A and one B you're AB type. If Mom is AA--she got an A allele from both parents--the child will be A. There's no choice. It's possible she got an A allele from one parent and an O from another, so if she's AO the child could inherit either her A allele (and be A blood type) or her O allele (and be O blood type) with 50 percent probability of either occurrence. Now for extra entertainment: Mom divorces Dad and remarries to someone with B blood type. If Mom is AO and new dad is BO, the child could be ANY blood type--there's a 25 percent probability the child could be AO, BO, AB or OO. And better, every child the AO/BO marriage produces could have a completely different blood type. You know the Duggar family, the ones with eighteen kids? If Mom was AO with both positive and negative Rhesus factor alleles, and Dad was BO with both Rhesus factor alleles, there could be eight different blood types in that family. Ain't genetics FUN?

Answer 4

In this situation there are only two different possibilities for the child. He or she will either be Type A (AO) or Type B (BO).

Answer 5

75% of A+ and 25% of O+ is possible(here + is dominant)

Answer 6

Genotype (DNA)

Blood Type

(+ , -) or (+ , +) Rh +

Answer 7

Parents of type A and type B may have children of any blood type. If more is known about whether the parents are heterozygous or homozygous, predictions may be made.

Answer 8

all childrens will be group O

Answer 9

No.
