Chapter 4, Problem 15P
A plant line with reduced fertility comes to the attention of a plant breeder who observes that seed pods often contain a mixture of viable seeds that can be planted to produce new plants, and withered seeds that cannot be sprouted. The breeder examines numerous seed pods in the reduced fertility line and counts
a. What single-gene mechanism best explains the breeder’s observation?
b. Propose an additional experiment to test the genetic mechanism you propose. If your hypothesis is correct, what experimental outcome do you predict?
