Question

In Antirrhinum, when a cross is made between red and white flowers all resultant progenies are

• A. Red
• B. Pink
• C. White
• D. Red and white in equal numbers

Answer 1

The correct option is B Pink

A genetic cross of inbred Antirrhinum majus with red flowers with inbred Antirrhinum majus with white flowers resulted in F${}_1$ hybrid offspring that all had pink flowers. When the F${}_1$ plants were self-pollinated, the resulting F${}_2$ generation plants had a phenotypic ratio of 1 red: 2 pink: 1 white.

So, the correct answer is option B.
