It is possible for their offspring to exhibit type AB, A, B, or O, depending upon the parental genotype, which is unknown. The blood type exhibited, also referred to as phenotype, is due to the dominant A and B alleles. Every person inherits two alleles for each gene, one from each parent. The type A may have inherited two A alleles or an A allele and an O allele, the O being masked by the dominant A because it is a recessive trait. Therefore they exhibit the phenotype A, but could potentially pass on an O allele to any offspring. The same goes for the type B parent (could be BB or BO). The exact genotype (AA/BB or AO/BO) is not determined through simple blood testing, so the exact phenotype of the offspring can not be predicted.

What problems will child suffer if a boy with blood group A positive marries a girl with blood group A negative?

If a boy with blood group A positive marries a girl with blood group A negative, their offspring may inherit one A allele from each parent. This means the child could have blood group A, which poses no health risks. However, if the child inherits the Rh factor from the father (positive) and the mother (negative), the child might have Rh incompatibility if the mother's blood enters the baby's bloodstream, which can lead to health issues in future pregnancies.

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.


What blood type (or types) can be found in an offspring of a mother has type O blood and the father as type B blood?

What blood type can be found if the mother has type AB blood and the father has type A blood?

If the father is homozygous for the B blood group, giving him the BB blood genotype, and the mother's genotype is AB (the only genotype for the AB blood group), then their offspring could have either the AB or B blood groups. If the father is heterozygous for the B blood group, giving him the BO genotype, then their offspring could have the AB, A, or B blood groups. However, they could not produce an offspring with the O blood group.
