Question

gregor mendel studied pea plants to determine the patterns of inheritance. what is not a reason mendel used pea plants in his experiments? check all that apply. they reproduced sexually. they were drought resistant. they had traits that were easy to observe. they only had two traits to study. done

Explanation:

1. For "They reproduced sexually": Sexual reproduction (involving gametes, fertilization) is key for studying inheritance as traits are passed via genes from parents. Mendel needed sexual reproduction to observe trait inheritance, so this is a reason he used pea plants, not a non - reason.
2. For "They were drought resistant": Mendel's experiments focused on inheritance of traits like flower color, seed shape, etc. Drought resistance was not relevant to his study of genetic inheritance patterns, so this is a non - reason.
3. For "They had traits that were easy to observe": Pea plants have distinct, easily observable traits (e.g., purple vs white flowers, round vs wrinkled seeds) which made it easy for Mendel to track inheritance, so this is a reason, not a non - reason.
4. For "They only had two traits to study": Pea plants have many traits (flower color, seed shape, pod color, etc.) that Mendel studied. The claim that they only had two traits is false, so this is a non - reason.

Answer:

B. They were drought resistant, D. They only had two traits to study
