Question

When the pollen from a yellow seeded pea plant was transferred to a green seeded pea plant, Mendel's observation was:

• A. All of the first-generation offspring bore yellow peas
• B. All of the first-generation offspring bore green peas
• C. Half of the first-generation offspring bore yellow peas
• D. Half of the first-generation offspring bore green peas

Hint:

In Mendelian inheritance, dominant traits (like yellow seeds) will express in the first generation, but recessive traits (like green seeds) appear in the second generation under certain conditions.

Answer 1

The Correct Option is C

Mendel's experiments with pea plants demonstrated the principles of inheritance. When he crossed a yellow-seeded pea plant with a green-seeded pea plant, he observed that all of the first-generation (F1) offspring had yellow seeds. This result was consistent with the dominant-recessive relationship of the seed color gene, where yellow is dominant over green. Thus, the offspring all displayed the dominant yellow trait, not green. However, Mendel's second-generation (F2) plants showed a 3:1 ratio of yellow to green seeds. Final Answer: \[ \boxed{\text{The correct answer is (3) Half of the first-generation offspring bore yellow peas.}} \]
