In Neurospora, the white-spore allele (ws) results in white spores rather than the wild-type black spores. Diploid ws / ws+ cells undergo meiosis followed by one round of mitosis to form ordered tetrads. Indicate if the pattern of spores seen in the tetrads are consistent with first-division or second-division segregation.

The pattern of spores (ws; ws; ws+; ws+; ws; ws; ws+; ws+) indicates a second-division segregation pattern, as the alleles segregate during the second meiotic division, resulting in a 4:4 arrangement of mutant and wild-type alleles in the tetrad.

In Neurospora, the White-Spore Allele (Ws) Results in White Spores
