Monohybrid cross Dihybrid cross

Monohybrid cross	Dihybrid cross
i.              Crosses involving a single pair of alleles are called monohybrid crosses. ii.            Monohybrid crosses yield a phenotypic ratio of 3:1 in the F2 generation. iii.           Genes are not assorted to form new recombination of characters.	i.              Crosses involving two pairs of alleles are called dihybrid crosses. ii.            Dihybrid crosses yield a phenotypic ratio of 9:3:3:1 in the F2 generation. iii.           Genes are assorted to form new combinations of characters.
