Vedclass · Answer

(A) In human blood group inheritance,the $ABO$ blood group system is controlled by the gene $I$. The gene $I$ has three alleles: $I^A$,$I^B$,and $i$. When the father contributes the $I^B$ allele and the mother contributes the $I^A$ allele,the resulting genotype of the offspring is $I^A I^B$. According to the principle of codominance,both $I^A$ and $I^B$ alleles are expressed equally in the presence of each other. Therefore,the individual with the genotype $I^A I^B$ will have blood group $AB$.

If the father gives $I^B$ allele and the mother gives $I^A$ allele,state the genotype and blood group of the offspring.
