A pea plant with purple flowers was crossed with white flowers producing all 50 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? Explain.

Explanation

These results are based on Principles of Laws of Inheritance, Law of Dominance and Law of Segregation In this experiment, a homozygous purple flower pea plant (PP) was first crossed with a white flowered pea plant resulting in 50 plants with only purple flowers On selfing these plants Le.. Pp in `F_2` the ratio Purple White was as given here: The result of this experiment given in the question also shows [482: 162] 3 : 1 ratio amongst purple coloured and white coloured flower plants
