      X/FM7a; αTub67C4/+ females show elevated levels of X chromosome nondisjunction.

      (Matthies et al., 1999)

      Eggs derived from females transheterozygous for αTub67Cunspecified and αTub67C4 have abnormal gonomeric spindles. Abnormal ectopic cleavage spindles form, the abnormality becoming more severe with time.

      (Mathe et al., 1998)

      No eggs from hemizygous females hatch. Many are apparently unfertilized, though insemination occurs. Paternal genotype has no effect on viability of progeny. Majority of eggs had 3 or fewer nuclei. This allele also shows a dominant reduction in female fertility.

      Based on average degree of development of eggs of the hemizygous mutant genotype the alleles can be ranked, from most to least severe, in the order αTub67C2 < αTub67C4 < αTub67C1 < αTub67C3. Based on the semidominant phenotypes the rank order is αTub67C3 < αTub67C1 = αTub67C2 = αTub67C4.
