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) axial and terminal flower position
B) yellow and green pea color
C) smooth and wrinkled pea shape
D) purple and white flowers
E) tall and short plant height

The Sbe1 gene is responsible for the production of starch-branching enzyme 1, which affects the texture of pea seeds. Allelic variation in this gene leads to differences in the starch structure within the peas, resulting in either smooth or wrinkled pea shapes.
