*
2 point
A. Maize and teosinte are genetically identical. The difference in morphology is the
result of growing under different environment (domesticated vs. wild).
B. During the process of domestication, mutations accumulated in the maize lineage,
O which are the main cause of the morphological differences between maize and
teosinte.
C. Pre-existing mutations in teosinte population were selected by humans during
domestication.
O
D. Humans developed maize by crossing teosinte with another species that has very
little auxiliary branching.
O
E. Maize and teosinte look so different from each other because they are not related
at all.
