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?

Fungi

Fungi can be single-celled or complex multicellular creatures. They are found in pretty much any natural surroundings; however, they generally live on the land, principally in soil or plant material instead of in the ocean or water. Fungi are the members of the group called the decomposers that live off dead and decaying matters. Fungi assume a significant part in the carbon cycle and its different components. They act as a parasite by causing illnesses like rusts, scabs, or ulcers. In crops, contagious illnesses can prompt critical money-related misfortune for the rancher. An exceptionally modest number of growths cause illnesses in creatures. In people, these incorporate skin illnesses such as competitors' feet, ringworm, and thrush.
