Step by step
Solved in 2 steps
- How do class A, B, and C genes in plants work together to determine the structures of the flower?Using the 'ABC model' of floral development, what would you expect the flowers of a mutant plant to look like if both A & B gene function had been destroyed?Monoecious plants such as corn have either staminate or carpelate flowers. Knowing what you do about the molecular mechanisms of floral development, which of the following might explain the development of single-sex flowers? a. Expression of B-type genes in the presumptive carpel whorl will generate staminate flowers. b. Loss of A-type genes in the presumptive petal whorl will allow C-type and B-type genes to produce stamens instead of petals in that whorl. c. Restricting B-type gene expression to the presumptive petal whorl will generate carpelate flowers. d. All of the choices are correct.
