Mendel concluded that pea traits like flower color were determined by separate units. From the results, Mendel proved that all traits do not blend. For instance, purple flowers mixed with white flowers did not produce pink flowers.
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. ... This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.
Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
Mendel's Results
Mendel noted the ratio of white flowered plants to purple-flowered plants was about 3:1. That is, for every three purple-flowered plants, there was one white flowered plant.
