If dwarf pea plant was treated with Gibberellic acid, it grew as tall as the pure tall pea plant. If this treated plant is crossed with a pure tall plant then the phenotypic ratio of is likely to be

All dwarf

$50\%$ dwarf $50\%$ tall

$75\%$ tall $25\%$ dwarf

All tall

(AIIMS-1980)

Solution

(d) All plants of $F_1$ generation are tall because gibberellic acid treated plant is genetically dwarf and behave like recessive individual and other one is dominant tall, thus according to Mendel's dominance law all plants of $F_1$ are tall.
