Mutations in Drosophila that are dominant and lethal when homozygous. Heterozygotes have a prolonged developmental period, and the adults are small, semisterile, with short thin bristles, rough eyes, etched tergites, and abnormal wing venation. Many Minutes are small deficiencies. There are at least 60 different Minute loci scattered throughout the genome, and some represent genes encoding ribosomal proteins.
