Analysis of a Strong Suppressor of Segregation Distorter in Drosophila melanogaster.

ABSTRACT: Segregation Di st orter (SD) is a naturally occurring male meiotic drive system in Drosophila melanogaster, characterized by almost exclusive transmission of the SD chromosome owing to dysfunction of sperm receiving the SD⁺ homolog. Previous studies identified at least three closely linked loci on chromosome 2 required for distortion: Sd, the primary distorting gene; E(SD) (Enhancer of SD), which increases the strength of distortion; and Rsp (Responder), the apparent target of Sd Strength of distortion is also influenced by linked upward modifiers including M(SD) (Modifier of SD) and St(SD) (Stabilizer of SD), and by various unlinked suppressors.
