Answer:
Gregor Mendel studied genetics by doing controlled breeding experiments with pea plants. Pea plants were ideal for genetics because, they reproduce quickly, they have easily observed traits, and Mendel could control which pairs of plants reproduced.
Explanation:
1. They reproduced quickly, this enabled Mendel to grow many plants and collect a lot of data.
2. They have easily observed traits, such as flower color and pea shape. This enabled Mendel to observe whether a trait was passed from one generation to the next.
3. Mendel could control which pairs of plants reproduced. This enabled him to determine which traits came from which plant pairs.
