Question

In Sweet Pea, the flower colour changes from Red to White and seed coat colour from grey to white. This is an example of

• A. Spontaneous mutation
• B. Pleiotropic mutation
• C. Reverse mutation
• D. Induced mutation

Answer 1

The correct option is B Pleiotropic mutation

Pleiotropy occurs when one gene will code and control the phenotype or expression of several different and unrelated traits. In pea plant. the same gene that affects the color of flower also influences the color of seed coat and the colour of leaf axil.

So, the correct answer is 'Pleiotropic mutation'.
