F1 plants that are medium in height are produced by crossing tall with short parents. When the F1 plants are self-fertilized, the F2 offspring consist of different heights ranging from short to tall with most plants having some intermediate height.

Now you want to further study the genetics of this trait and, for that, you grow the F2 offspring in a field location in the summer of 2019 (all in the same field which is subject to similar conditions and management practices including fertilizer application, irrigation, etc.). You then measure the variation observed for plant height. Under this scenario, what would you expect to be causing most of the variation you are seeing in plant heights?

a) Incomplete Dominance

b) Linkage

c) Genetic differences between plants

d) Environmental effects
