Question

A pea plant with purple flowers was crosSed with white flowers producing 60 plants with only purple flowers.
On selfing, these plants produced 482 plants with purple flowers and 162 with white flowers. What genetic mechanism accounts for these results.

Answer 1

Genetic Mechanism - Prinicipal of Dominance : Mendel studied inheritance of seven constrasting traits. One trait dominates over the other and is expressed that, generation, where as the other is not expressed and remains recessive.
The results of `F_2` generation, however showedt hat the recessive character re appears and In a definite ratio, The `T_2` ratio in each experiment was invariably 3:1 ratio. Approximately the three fourths of them were dominant type and one fourth were the recessive type.
The result is obtained due to segregation of the alleles at the time of gametogenesis. The alleles remain together is a zygote but during gamete formation, they segregate such that the gametes carry only one allenle
