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" is incorrect because pea plants have multiple traits (e.g., seed shape, flower color).
• "They produce flowers" is not a unique or key reason for Mendel's choice, as many plants produce flowers.
• "They grow very slowly" is incorrect; pea plants have a relatively short generation time, which is beneficial for experiments.
• "They reproduce sexually" is correct. Sexual reproduction allows for the combination of genetic material from two parents, which is essential for studying inheritance patterns (Mendel studied how traits are passed from parents to offspring, and sexual reproduction provides the genetic variation and inheritance mechanisms he could observe).

Answer:

D. They reproduce sexually
