Vedclass · Answer

(C) To determine the possible genotypes and phenotypes of the children, we perform a Punnett square cross between the parents with genotypes $I^AI^B$ and $I^Ai$.Parental gametes:Parent $1$ $(I^AI^B)$: $I^A, I^B$Parent $2$ $(I^Ai)$: $I^A, i$Punnett Square:- $I^A 	imes I^A = I^AI^A$ (Blood type $A$)- $I^A 	imes i = I^Ai$ (Blood type $A$)- $I^B 	imes I^A = I^AI^B$ (Blood type $AB$)- $I^B 	imes i = I^Bi$ (Blood type $B$)Possible Genotypes: $I^AI^A, I^Ai, I^AI^B, I^Bi$ (Total $4$ distinct genotypes).Possible Phenotypes: Blood type $A$, Blood type $AB$, Blood type $B$ (Total $3$ distinct phenotypes).Therefore, the correct answer is $4$ genotypes and $3$ phenotypes.

The genotypes of a husband and wife are $I^AI^B$ and $I^Ai$ respectively. How many different genotypes and phenotypes are possible among their children?
