Abstract

Fs(2)1 is a germ-line dependent dominant female sterile mutation of Drosophila melanogaster. Fs(2)1 heterozygous females deposit very few abnormal eggs (collapsed, with malformed chorion). The degeneration of egg primorida starts around the end of egg maturation. Mitotic recombination mapping locates Fs(2)1 in a distal region of the left arm of the 2nd chromosome. Fs(2)1 is a good tool for studying germ-line functions (by the dominant female sterile technique) because the frequency of germ-line mosaicism exceeds 20% upon irradiation of adult females. Salivary gland polytene chromosomes of Fs(2)1 and the revertant heterozygous larvae appear normal.
