A Neurospora colony at the edge of a plate seemed to be sparse (low density) in comparison with the other colonies on the plate. This colony was thought to be a possible mutant, and so it was removed and crossed with a wild type of the opposite mating type. From this cross, 100 ascospore progeny were obtained. None of the colonies from these ascospores was sparse, all appearing to be normal. What is the simplest explanation of this result? How would you test your explanation? (Note: Neurospora is haploid.)

Question
A Neurospora colony at the edge of a plate seemed to be
sparse (low density) in comparison with the other colonies on the plate. This colony was thought to be a possible mutant, and so it was removed and crossed with a
wild type of the opposite mating type. From this cross,
100 ascospore progeny were obtained. None of the colonies from these ascospores was sparse, all appearing to
be normal. What is the simplest explanation of this result? How would you test your explanation? (Note:
Neurospora is haploid.)
