In F2 generation of Mendel’s Monohybrid cross the phenotypic ratio is approximately 3 red : 1 white.
1. The F2
generation had both red-flowered and white-flowered plants.
2.
Mendel found out that out of the total of 929 pea-plants, 705 bore redflowers and
224 plants were with white flowers.
3.
Therefore, the phenotypic ratio is approximately 3 red : 1 white.
