Problem
Two pure lines of plants are crossed, one with yellow petals and one with red. They are all orange. When the Fis selfed to give an F, we find the following result: 112 Orange: 182 Yellow: 61 Red: 77. You consult an expert who says that these results could be explained by two competing hypotheses: incomplete dominance and recessive epistasis.
1) Describe how incomplete dominance could explain these results.
a) Normalize ratios: 2.9: 1:1.26
b) We have a genotypical ratio of 1:2:1 for incomplete dominance (No match)
c) Also no blending
2) Describe how recessive epistasis could explain these results.
