I got this question in an interview for internship.

This intriguing question comes from Inheritance of One Gene-2 in chapter Principles of Inheritance and Variation of Biology – Class 12

Correct answer is (d) 25% white and 75% violet

To elaborate: Violet is dominant over white. Self-crossing of violet flowered plants will produce 25% recessive plants, which will have white-flowers.
