Question

how did mendel control which plants were being pollinated?
he used artificial cross-pollination.
he only used female plants for this.
he allowed any plant to be pollinated.

Explanation:

To determine how Mendel controlled pollination, we analyze each option:

• Option 1: Mendel used artificial cross - pollination. He would remove the anthers (male parts) of a flower to prevent self - pollination and then transfer pollen from the desired male flower to the female part of the target flower. This is a well - known method he used to control which plants were pollinated.
• Option 2: Plants have both male and female reproductive structures in many cases (especially pea plants which Mendel worked with), and he didn't only use female plants. So this option is incorrect.
• Option 3: If he allowed any plant to be pollinated, he wouldn't be able to control the pollination process, which is essential for his genetic experiments. So this option is incorrect.

Answer:

A. He used artificial cross - pollination.
