Who was Gregor Mendel and why was he important?
|
|
Definition
| Gregor Mendel is a scientist who conducted experiments about geneticswith pea plants. He is inportant because he was the first to understand genetics and all work on genetics is based off of his |
|
|
Term
What plants did Mendel use for his experiments and what were the seven traits he studied?
|
|
Definition
| Mendel used pea plants for his experiments. Flower color, flower position, seed color, seed shape, pod shape, pod color, and stem length. |
|
|
Term
| Why were these plants good for conducting experiments? |
|
Definition
| Because there are only two possible forms of a trait so it is easy to track inheritance and they are easy to grow and the reproduce quickly |
