FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Embryos laid by γTub37Cunspecified mutant mothers show no signs of spindle formation or nuclear division.
Eggs derived from homozygous females show no visible sign of embryonic development when observed under transmitted light in a stereo microscope. After 4-6 hours after egg deposition the originally unformly dense (like wild type) yolk mass starts to disintegrate into a network of darker and lighter yolk droplets. The defect may be in fertilisation or very early in embryonic development.
