Why did Mendel choose to work with peas?
Why did Mendel choose to work with peas?
- Peas are easy to control and manipulate for breeding experiments.
- Peas have a short generation time and produce a large number of offspring. (correct)
- Peas have multiple varieties with distinct traits such as flower color.
- Peas have both stamens and carpels in each flower, allowing for self-fertilization.

- They were genetically modified to express specific traits.
- They had a variety of different traits for the same character.
