Question

why did mendel study pea plants?
○ they reproduce asexually and have one trait that is easy to observe.
○ they reproduce asexually and have many traits that are easy to observe.
○ they reproduce sexually and have one trait that is easy to observe.
○ they reproduce sexually and have many traits that are easy to observe.

Explanation:

Mendel chose pea plants because they reproduce sexually (via pollination, including self - pollination and cross - pollination which is a form of sexual reproduction in plants) and have many distinct traits (like flower color, seed shape, etc.) that are easy to observe and study. The first two options are wrong as pea plants reproduce sexually, not asexually. The third option is wrong because they have many, not one, observable traits.

Answer:

D. They reproduce sexually and have many traits that are easy to observe.
