F1 plants that are medium in height are produced by crossingtall with short parents. When the F1 plants are self-fertilized,the F2 offspring consist of different heights ranging from short totall 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 thesummer of 2019 (all in the same field which issubject to similar conditions and management practices includingfertilizer application, irrigation, etc.). You then measure thevariation observed for plant height. Under this scenario, whatwould you expect to be causing most of the variation you are seeingin plant heights?
a) Incomplete Dominance
b) Linkage
c) Genetic differences between plants
d) Environmental effects
