Question 1 - MCQ questions - Chapter 9 Class 10 - Heredity and Evolution (Term 2)

If a round, green seeded pea plant (RRyy) is crossed with wrinkled, yellow seeded pea plant, (rrYY) the seeds produced in F1 generation are

(a) round and yellow.

(b) round and green.

(c) wrinkled and green.

(d) wrinkled and yellow.
