Vedclass · Answer

(C) The blood group of an individual is determined by the $ABO$ gene, which has three alleles: $I^A$, $I^B$, and $i$.Parents with blood group $AB$ have the genotype $I^A I^B$.When these parents produce gametes, each gamete will carry either the $I^A$ allele or the $I^B$ allele.Possible combinations for the offspring are:$I^A 	imes I^A = I^A I^A$ (Blood group $A$)$I^A 	imes I^B = I^A I^B$ (Blood group $AB$)$I^B 	imes I^A = I^A I^B$ (Blood group $AB$)$I^B 	imes I^B = I^B I^B$ (Blood group $B$)Thus, the possible blood groups for the children are $A$, $B$, and $AB$.The blood group $O$ (genotype $ii$) cannot be produced because neither parent carries the recessive $i$ allele.

If both parents have blood group $AB$, which blood group cannot be found in their child?
