Question

Quizplus · Accepted Answer

The APETALA-2 gene represses the expression of AGAMOUS in whorls 1 and 2, helping to determine the floral organ identity by preventing the activation of genes responsible for the development of reproductive organs (stamens and carpels) in the outer floral whorls.
