Question

A tall pea plant with round seeds (TTRR) is crossed with a dwarf wrinkle seeded plant (ttrr). $F_1$ has tall plants with rounded seeds. What is the proportion of dwarf plants with wrinkled seeds in $F_2$ generation

• A. Zero
• B. 1/2
• C. 1/4
• D. 1/16

Answer 1

The correct option is D 1/16

A pure Tall plant with round seeds(TTRR) is crossed to pure dwarf plants with wrinkled seeds(ttrr). In the F₁ generation plants with tall plants with round seeds(TtRr) are formed. When F₁ individuals are subjected to self pollination, in the F₂ genearation, 9 plants are tall with round seeds, 3 plants are tall with wrinkled seeds, 3 plants are Dwarf with round seeds, 1 plant is dwarf with wrinkled seeds are formed.

So, the correct option is ‘1/16’.
