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.
