Question

If pea plants with round and green seeds (RRyy) are crossed with pea plants having wrinkled and yellow seeds (rrYY), the seeds developed by the plants of F₁ generation will be ______.

पर्याय

• 50% round and yellow

• 75% wrinkled and green

• 100% round and yellow

• 75% wrinkled and yellow

Answer 1

If pea plants with round and green seeds (RRyy) are crossed with pea plants having wrinkled and yellow seeds (rrYY), the seeds developed by the plants of F₁ generation will be 100% round and yellow.

Explanation:

• Round (R) is dominant over Wrinkled (r).
• Yellow (Y) is dominant over Green (y).
• Crossing RRyy (Round, Green) × rrYY (Wrinkled, Yellow) results in all F₁ offspring having RrYy (Round, Yellow) because they inherit one dominant allele for each trait.

Thus, all F₁ generation seeds will be round and yellow.
