Heterozygous strains were sporulated and dissected into tetrads. The expected and actual number of segregants with the indicated genotype is presented. The arrow highlights the observed result that does not correlate with expectations. Expected values were calculated on the basis of the predicted segregation frequencies of each of the three heterozygous markers (0.5 × 0.5 × 0.5).
