(B) In a dihybrid cross involving two traits (e.g.,$AaBb 	imes AaBb$),the $F_2$ generation produces $16$ combinations of genotypes.Among these,the parental genotypes are the homozygous dominant $(AABB)$ and the homozygous recessive $(aabb)$.There is $1$ individual with the $AABB$ genotype and $1$ individual with the $aabb$ genotype.Therefore,the total number of individuals with parental genotypes is $1 + 1 = 2$.The proportion of these individuals in the $F_2$ generation is $2/16$.

During a dihybrid cross with contrasting characters,in the $F_2$ generation,what is the proportion of individuals with parental genotypes (in $/6$)?
