Question

In a cross between red coloured and white coloured flowers, when plants with red coloured flowers of F₁ generation were self pollinated, plants of F₂ generation were obtained in which 75% of plants were with red flowers and 2.5% plants were with white flowers.

Explain the inheritance of traits in the above cross with the help of a flow chart only along with the ratio of plants obtained.

Answer 1

A plant with pure red flowers will generate plants with red blooms when crossed with a plant with pure white flowers. It is called Mendel's Monohybrid cross.

• Phenotypic ratio: Red : White : 3 : 1
• Genotypic ratio: Pure Red : Hybrid Red : Pure White : 1 : 2 : 1
