Mendel’s Dihybrid Cross and Trait Ratios

Mendel’s dihybrid cross shows how two traits are inherited at the same time. A dihybrid cross is a cross in which both parents are homozygous for two distinct traits, and the F1 generation is heterozygous for both traits.

Gregor Mendel’s first experiments showed that units called genes help pass traits from parents to offspring.

Each organism has two copies of each gene, called alleles, with one inherited from each parent.

Mendel’s next experiment used dihybrid crosses of pea plants that differed in two traits, such as height and flower color, to test...
