Question

why did gregor mendel use peas in his experiments?
peas grow very slowly.
pea reproduction cannot be controlled.
peas normally produce very few offspring.
peas have characteristics that have two forms.

Explanation:

To determine why Gregor Mendel used peas, we analyze each option:

• "Peas grow very slowly" is incorrect as peas have a relatively short generation time, which is beneficial for experiments.
• "Pea reproduction cannot be controlled" is wrong because Mendel could control pea reproduction (e.g., through cross - pollination and self - pollination).
• "Peas normally produce very few offspring" is false; peas produce a large number of offspring, which is good for statistical analysis in experiments.
• "Peas have characteristics that have two forms" is correct. For example, pea plants have traits like tall/short, yellow/green seeds, etc., which have two distinct forms, making them ideal for studying inheritance.

Answer:

D. Peas have characteristics that have two forms. (Note: Assuming the options are labeled A - D in order, with the last option being D. If the original labeling is different, adjust the identifier accordingly, but the text of the option remains the same.)
