In the fungus Neurospora,a strain that was auxotrophic for thiamine (mutant allele t)was crossed to a strain that was auxotrophic for methionine (mutant allele m).Linear asci were isolated,and they were classified in the following groups:

a)Determine the linkage relationships of these two genes to their centromere(s)and to each other.Specify distances in map units.

b)If 1000 randomly selected ascospores are plated on a plate of minimal medium,how many are expected to grow into colonies?
