Dihybrids, dihybrid cross

- Mendel identified his second law of inheritance by following two characters at the same time - Crossing two true-breeding parents differing in two characters produces dihybrids in the F1 generation, heterozygous for both characters - A dihybrid cross, a cross between F1 dihybrids, can determine whether two characters are transmitted to offspring together as a unit or independently [SEE IMAGE]
