Results of crosses of a large number of Neurosporas of different origin, including several distinct strains of N. sitophila, were utilized to re-examine the question of whether certain wild-type Neurosporas other than N. crassa show biases in the two types of second-division segregation. Segregations for alleles of the mating type and peak loci on a wide variety of genetic backgrounds gave little evidence for excess either of symmetrical or asymmetrical ‘post-reduction’ asci.
