Genes don't blend.
Gregor Mendel explains that breeding short and tall pea plants didn't produce a medium-sized plant.
To my surprise, I found that none of the individual traits I studied were blended in the offspring of a cross between two pure-bred parents. Furthermore, in the hybrid offspring, only one of the two traits was seen. I then had to figure out why only one trait was seen in the hybrid offspring of the pure-bred crosses.

Mendel discovered that pure-bred plants did not produce offspring with blended traits.
Animation 12 George Shull used corn to study gene variation.
Mendel deduced that pure-bred parents have two copies of the same gene for each trait.
