Vedclass · Answer

(D) The inheritance of blood groups is determined by multiple alleles. For a child to have blood group '$O$' (genotype $ii$),both parents must contribute an 'i' allele.Since both parents have blood group '$A$',their genotypes must be $I^A I^A$ or $I^A i$.If a child has blood group '$O$' $(ii)$,it implies that both parents must carry the recessive 'i' allele.Therefore,both parents must be heterozygotic for blood group '$A$',with the genotype $I^A i$.When both parents are $I^A i$,the possible genotypes for the offspring are $I^A I^A$ (blood group $A$),$I^A i$ (blood group $A$),and $ii$ (blood group $O$).

Mother and father both have blood group '$A$'. They have two children,one with blood group '$O$' and the second one with blood group '$A$'. They have:
