The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid.

b) Neurospora has an arginine amino acid synthesis pathway shown below. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not with ornithine supplements. Assuming gens A, B, and C are unlinked and there is only one mutation per stain:

What percentage of the progeny will grow on ornithine?

What percentage on citrulline?

What percentage on arginine?
