A pea plant with purple flowers was crossed with white flowers producing, 50 plants with only purple flowers. On selfing, the plants produced 470 plants with purple flowers and 160 with white flowers. Explain the genetic mechanism accounting for the above results.

Explanation

In `F_(2)` generation ratio of purple to white flowers is appoximately `3:1` so that ratio can be classified under Mendelian monohybrid cross.The cross further explain for followin facts:
(a)`F_(1)` is represented only by one of the parental forms i.e., purple flowered plants.
(b)Both the parents i.e., purple and white flowered plants appear in `F_(2)` generation
