| Gregor Mendel used ____ to study the inheritance of traits. | pea plants |
| Mendel removed the male parts from the flowers of some plants in order to ___. | prevent self-pollination |
| Mendel's "factors" would eventually be called ___. | genes |
| Mendel noticed that each "factor" in pea plants had two "forms." These "forms" would later be called ___. | alleles |
| When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, the offspring were ___. | all tall |
| The person considered to be the father of genetics is ___. | Gregor Mendel |
| If the offspring from a true-breeding tall plant and a true-breeding short plant are allowed to self-pollinate, they will produce offspring in the F2 generation that are ___. | about 75% tall and 25% short (Remember, it asked about the F2 generation. The true-breeding parents would be the P generation. Their offspring who were allowed to self-pollinate were the F1 generation. The offspring that resulted from the self-pollination were the F2 generation) |
| Plants with the ___ form of a trait are always true-breeding. | recessive |
| Plants with the ____ form of a trait can be true-breeding while other plants with that trait might not be true-breeding. | dominant |
| True-breeding plants that produced constricted pods were crossed with true-breeding plants that produced inflated pods. The resulting offspring produced inflated pods. It can be concluded that the ____ pod allele is dominant. | inflated |
| When alleles ___ from each other, they separate. | segregate |
| Alleles segregate from each other when ___ form during the process of ___. | sex cells form during the process of meiosis. |
