Fig 1. Overview of STSS.

Minimal requirements for each strain to be used in STSS, including true-breeding population with conditional Y-linked lethality (a) or conditional X-linked lethality (b). (c) Mating scheme in absence of lethal gene repressor. Combining non-transgenic females produced from the YL strain with adult flies from the XL strain results in death of all offspring except for non-transgenic males. This includes offspring from mating events of XL males and females. Tet, tetracycline.
