Vedclass · Answer

(A) The mother is homozygous for blood group $B$,so her genotype is $I^B I^B$. The father has blood group $A$,which could be homozygous $(I^A I^A)$ or heterozygous $(I^A I^O)$.If the father is $I^A I^A$,the cross is $I^B I^B 	imes I^A I^A$,resulting in $I^A I^B$ (blood group $AB$).If the father is $I^A I^O$,the cross is $I^B I^B 	imes I^A I^O$,resulting in $I^A I^B$ (blood group $AB$) and $I^B I^O$ (blood group $B$).Combining these possibilities,the progeny can have blood groups $AB$ and $B$.

Mother is homozygous for blood group $B$,and father has blood group $A$ (genotype unknown). Therefore,the possible blood groups in the progeny are:
