Vedclass · Answer

(B) The $ABO$ blood group system is determined by three alleles: $I^A, I^B$,and $i$. Individuals with type $B$ blood can have the genotype $I^B I^B$ (homozygous) or $I^B i$ (heterozygous). Individuals with type $O$ blood must have the genotype $ii$. If the man is $I^B I^B$,the cross is $I^B I^B 	imes ii$,resulting in all offspring having the genotype $I^B i$ (Type $B$ blood). If the man is $I^B i$,the cross is $I^B i 	imes ii$,resulting in offspring with genotypes $I^B i$ (Type $B$ blood) and $ii$ (Type $O$ blood). Therefore,the children could have either Type $B$ or Type $O$ blood.

With regard to the $ABO$ blood typing system,if a man who has type $B$ blood and a woman who has type $O$ blood were to have children,what blood types could the children have?
