Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow

An autotroph is an organism that can produce it's own food. For example, a plant is an autotroph, as it uses photosynthesis to produce is food. There are also some autotrophs that are not plants, so don't get confused between the two!
