Question

Study the following and select the correct statements.

(I) $F_1$ progeny is the first hybrid generation and progeny resembled either of the parents.
(II) $F_2$ progeny is a resultant hybrid generation of cross-pollination among $F_1$ progeny and progeny showed both dwarf and tall plants.
(III)$F_2$ progeny is a hybrid generation, produced by selfing $F_1$ hybrids and progeny contained both dwarf and tall plants.
(IV) The proportion of probability of plants that dwarf was 1/4 that of the $F_2$ plants while 3/4th of the plants were tall.

• A. I, II, III, IV
• B. I, III, IV
• C. I, II, IV
• D. III, IV

Answer 1

Answer: (B)

I, III, IV

• $F_1$ is the first generation of hybrid. This is also known as the first filial generation. This generation resembles exactly one of the parental types.
• The $F_2$ progeny is obtained by making self-pollination between the $F_1$ progeny.Two $F_1$ progenies selected are self-pollinated and the $F_2$ progeny is obtained and it can't be cross-pollinated.

The correct answer is option B.
