Question

Give an example of how you could determine whether or not a trait was displaying incomplete dominance. What would you do? What would your results have to be for the trait to be incomplete dominant?

Answer 1

Answer:

If one has to find that whether a trait is showing incomplete dominance, then post-mating the two species should produce an offspring that will demonstrate an intermediate character of the two parents. For example, in snapdragon flower, when red-colored flowers were crossed with the white one, the F1 generation exhibited all pink flowers, that is, a trait, which is an intermediate between the two.  

The outcomes, which shows that whether a trait is incomplete dominant are that the F1 generation should exhibit an intermediate character of the two parents, and the F2 progeny should exhibit a phenotypic and genotypic ratio of 1:2:1.  

Answer 2

An example of incomplete dominance is: A snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower when neither the white or the red alleles are dominant.
