  1. Two related species depending on the same prey species avoid competition by feeding at different times of the day.

  2. The body sizes of two related species are very similar when they are allopatric but in geographical areas of sympatric, one species is significantly smaller than the other
  3. The food niche of a species is generally wider in the absence of competing species than in their presence.
  4. Closely related species can coexist if their densities are regulated by a predator

In this problem we will explore some of the many ways that mutations in two different genes can interact to produce different Mendelian ratios. Consider a hypothetical insect species that has red eyes. Imagine mutations in two different unlinked genes that can, in certain combinations, block the formation of red eye pigment yielding mutants with white eyes. In principle, there are two different possible arrangements for two biochemical steps responsible for the formation of red eye pigment. The two genes might act in series such that a mutation in either gene would block the formation of red pigment. Alternatively, the two genes could act in parallel such that mutations in both genes would be required to block the formation of red pigment.
Further complexity arises from the possibility that mutations in either gene that lead to a block in enzymatic activity could be either dominant or recessive. If the crosses is made between a wild type insect with red eyes and a true breeding white eyed strain with mutations in both genes. Such considerations yield the Pathways in series with recessive mutations in both genes, what will be the phenotype in F1 progeny?
