Vedclass · Answer

(b): If the genotypes of husband and wife are $I^AI^B$ and $I^Ai$ respectively, then the probabilities of genotypes and phenotypes among their children can be worked out as:


	
		
			Genotype:
			$I^A I^A$
			$ I^Ai$
			$ I^AI^B$
			$I^Bi$
		
		
			Phenotype:
			$A$
			$A$
			$AB$
			$B$
		
	


Thus, there are four possible genotypes, viz., $I^AI^A, I^Ai, I^AI^B$ and $I^Bi$ and three possible phenotypes, viz., $A, AB$ and $B$ among the children.

The genotypes of a husband and wife are $I^AI^B$ and $I^Ai$. Among the blood types of their children, how many different genotypes and phenotypes are possible?
