Question

Find the correct statements
(i) $F_1$ progeny is the first hybrid generation and progeny resembles either of a parent.
(ii) $F_2$ progeny is a resultant hybrid generation of cross-pollination among $F_1$ progeny and the progeny shows both dwarf and tall plants.
(iii) $F_2$ progeny is the second hybrid generation produced by selfing $F_1$ hybrids and progeny contains both dwarf and tall plants.
(iv) Proportion of probability of plants that are dwarf is 1/4 of $F_2$ plants while 3/4 of $F_2$ plants are tall.

• A. i, ii, iii, iv
• B. i, iii, iv
• C. i, ii, iv
• D. iii, iv.

Answer 1

The correct option is B i, iii, iv

i)F₁ progeny is first hybrid generation and progeny resembles either of parent – True.

ii)F₂ progeny is a resultant hybrid generation of cross pollination among F₁ progeny and the progeny shows both dwarf and tall plants – False, because F₂ progeny is a resultant hybrid generation of cross pollination among F₁ progeny and the progeny shows either dwarf or tall plants.

iii)F₂ progeny is second hybrid generation produced by selfing F₁ hybrids and progeny contains both dwarf and tall plants – True.

iv)Proportion of probability of plants that are dwarf is ¼ of F₂ plantss while ¾ of F₂ plants are tall – True.

So the correct answer is option B.
