Term
| He crossed purebred tall-stemmed pea plants with purebred short-stemmed pea plants. The first generation, or the F1 generation all had TALL stems. Later, he let the F1 plants to self pollinate, and the new second generation or the F2 generation were about 75 percent TALL and 25 percent SHORT! |

Definition
| How mamny letters are to be in each allele combination?? |
|
|
Term
| Use the first letter in the dominant allele name. Example: In Mendal's experiment, he tested the pea shape. The Dominant trait was round and the the Recessive was wrinkled. The letter you would use would be "R" for the dominant trait, Round. |
