1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.

Option D

<h3><u>Explanation:</u></h3>

The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.

He crossed them to get all tall plants in 1^{st} Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is 1/4^{th} of the total population of F2 generation.
