The two-factor crosses performed by Mendel support the observation that A)alleles of one gene are distributed randomly among an individual's gametes,independent of the alleles for other genes. B)traits that are encoded by genes on different chromosomes are never found within the same gamete. C)the F₁ generation can display phenotypes in combinations different from those seen in the P generation. D)the F₂ generation will only display phenotypes in the same combinations as the P generation. E)self-fertilization of the F₁ generation will produce 100% heterozygous plants at both loci.

The two-factor crosses performed by Mendel, specifically his experiments with dihybrid crosses, showed that alleles of different genes are distributed independently into gametes. This principle is known as the law of independent assortment, which supports choice A.
