(B) In a dihybrid cross,the $F_1$ generation produces $AaBb$ individuals. When $AaBb$ is self-crossed to produce the $F_2$ generation,the phenotypic ratio follows Mendel's Law of Independent Assortment.For a dihybrid cross involving two traits,the phenotypic ratio of the $F_2$ generation is $9 : 3 : 3 : 1$.This ratio represents the four possible phenotypes: both dominant,one dominant and one recessive,one recessive and one dominant,and both recessive.
