Assume that a cross is made between tall and dwarf tobacco plants. The F1 generation showed intermediate height, whereas the F2 generation showed a distribution of height ranging from tall to dwarf, like the original parents, and many heights between the extremes. These data are consistent with which one of the following modes of inheritance?
A) codominance
B) incomplete dominance
C) hemizygosity
D) multiple -factor inheritance
E) alternation of generations

Question
