The genes responsible for some of the traits that Mendel observed have been recently identified and have helped in determining how molecular variation produces morphologic variation in pea plants. Allelic variation in the Sbe1 gene, which produces starch-branching enzyme 1, is responsible for which trait in peas?
A)round and wrinkled pea shape
B)yellow and green pea color
C)purple and white flowers
D)tall and short plant height
E)axial and terminal flower position
