Compare and contrast the blending and particulate models of heredity
What will be an ideal response?
The blending model of heredity suggested that the offspring would show a blending of traits from the mother and father. The offspring would always show phenotypes intermediate to those of the parents. In the particulate model of heredity, "particles" governing traits would retain their identity from generation to generation. The final phenotype in the offspring would be governed by rules other than blending.

In Drosophila, the wild-type eye color is red. A mutation, vermilion, causes vermilion-colored eyes, unless there is a mutation in another gene, suv, which, when homozygous or hemizygous, results in eyes that are the wild-type red even in the
