Which statement best describes Mendel's experiments?

A. he began with hybrid plants
B. he controlled pollination
C. he only observed one generation
D. he used plants that reproduced slowly

B

Explanation:

Mendel needed to control the plants' pollination, because he wanted to selectively breed the plants and observe the results.

Why not A: He began with purebreeding plants, so he could trace alleles exactly.

Why not C: He observed so many generations! It's important in an experiment to have as large a sample size as you can without being too large.

Why not D: Part of the reason he picked pea plants is because they reproduce quickly, so he could measure efficiently.
