The combination of a yellow leaf plant and a green leaf plant produces yellow leaves

In one of most classic examples,Mendel combined a purebred yellow-seeded plant with a purebred green-seeded plant,and he got only yellow seeds.He called the yellow-colored trait the dominant one,because it was expressed in all the new seeds. Then he let the new yellow-seeded hybrid plants self-fertilize.And in this second generation,he got both yellow and green seeds,which meant the green trait had been hidden by the dominant yellow.He called this hidden trait the recessive trait.From those results, Mendel inferred that each trait depends on a pair of factors,one of them coming from the mother and the other from the father.
