A cross between a red flower bearing plant and a white flower bearing plant of Antirrhinum produced all plants having pink flowers. Work out a cross to explain how this is possible.

Explanation

To explain the inheritance of flower color in Antirrhinum (snapdragon), we can analyze the cross between a red flower-bearing plant and a white flower-bearing plant, which results in all offspring having pink flowers. This phenomenon can be understood through the concept of incomplete dominance.
