Question

Two pen plants, one with round green seeds (RRyy) and another with wrinkled yellow (rrYY) seeds were crossed with each other which produced F₁ progeny that have only round yellow (RrYy) seeds. When F₁ plants are self-pollinated, the F₂ progeny will have which new combination of characters, as compared to the parents:

1. Round, yellow
2. Round, green
3. Wrinkled, yellow
4. Wrinkled, green

पर्याय

• (i) and (ii)

• (i) and (iv)

• (ii) and (iv)

• (i) and (iii)

Answer 1

(ii) and (iv)

Explanation:

The parental combinations were Round, green (RRyy) and Wrinkled, yellow (rrYY). Due to the independent assortment of genes, self-pollinating the F₁ generation generates two new character combinations that neither parent possessed: (ii) Round, green and (iv) Wrinkled, green.
