A child is born to a mother with blood type A and a father with blood type B. Assuming that both parents are heterozygous. What is the possibility that the child will have the blood type AB? go

To determine the possibility of the child having blood type AB, we need to consider the genotypes of the parents and the possible combinations of alleles that the child can inherit.<br /><br />Given that both parents are heterozygous, the mother has genotype AO and the father has genotype BO.<br /><br />The possible combinations of alleles that the child can inherit are:<br />- AO (from the mother)<br />- BO (from the father)<br /><br />The possible genotypes of the child are:<br />- AA (if the child inherits A from both parents)<br />- AB (if the child inherits A from the mother and B from the father)<br />- AO (if the child inherits O from both parents)<br />- BO (if the child inherits B from both parents)<br /><br />Out of these possible genotypes, only one (AB) results in the child having blood type AB. Therefore, the probability of the child having blood type AB is 1 out of 4, or 25%.
