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:

To determine the correct answer, we analyze each option:

• "They exhibit only a single trait": Pea plants have multiple traits (e.g., seed shape, flower color), so this is incorrect.
• "They produce flowers": Many plants produce flowers, and this is not a unique reason for Mendel's choice.
• "They grow very slowly": Pea plants have a relatively short generation time (grow quickly), so this is incorrect.
• "They reproduce sexually": Sexual reproduction allows for the study of inheritance patterns (e.g., segregation and independent assortment of traits), which was key to Mendel's work.

Answer:

D. They reproduce sexually
