P-element insertion into the sn gene.
female sterile | recessive
lethal - all die during embryonic stage | maternal effect | recessive
some die during embryonic stage | recessive | maternal effect | recessive
dorsal appendage
egg | maternal effect
orbital bristle
Ultrastructural analysis shows that orbital bristles are gnarled and have irregular striations in mutant males.
Homozygous females lay eggs with abnormal dorsal appendages that fail to hatch.
A sn allele has been induced by IR hybrid dysgenesis. It is stable.
P-element repressor proteins repress Ecol\lacZ expression in the somatic follicle cells but not in the germline cells of the ovary.
