... Mendel used garden peas: yellow and green, smooth and wrinkled. It was a good choice because: 1) there are a number of characteristics expressed one of two ways, which made it easier to see which had been inherited and which was dominant/recessive. 2) the plant reproduced two ways - sexually and ase ...

Variation Hardy

Notwithstanding this, the alleles of individual genes have a large effect on the characteristic. Continuous Variation ...
