Solution

## 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.
