What was the greatest usefulness of pea plants in Mendel's experiments?
Answer and explanation
Correct answer: Clear contrasting traits and ease of controlled crossing
The governing concept is experimental suitability in Mendelian genetics. Pea plants offered several clear, contrasting traits, such as tall versus dwarf and round versus wrinkled seeds, making inheritance patterns easy to observe. They also self-pollinate naturally but can be cross-pollinated by hand, allowing Mendel to control the parent plants. Therefore option A is correct; the other choices contradict the useful features of peas.
