Question

what is one of the reasons why gregor mendel chose to study pea plants?
they exhibit only a single trait.
they produce flowers.
they grow very slowly.
they reproduce sexually.

Explanation:

Mendel chose pea plants for several reasons. Pea plants reproduce sexually, which allows for the study of inheritance patterns. They have distinct traits that are easy to observe and track. Producing flowers is a general plant characteristic and not a specific reason for Mendel's choice. Pea plants do not exhibit only a single trait. Also, pea plants do not grow very slowly; in fact, they have a relatively short generation time which was beneficial for Mendel's experiments.

Answer:

They reproduce sexually.
