CRISPR/Cas gene drives can bias transgene inheritance through different mechanisms. Homing drives are designed to replace a wild-type allele with a copy of a drive element on the homologous chromosome. InAedes aegypti, the sex-determining locus is closely linked to thewhitegene, which was previously used as a target for a homing drive element (wGDe). Here, through an analysis using this linkage we show that in males inheritance bias ofwGDedid not occur by homing, rather through increased propagation of the donor drive element. We test the samewGDedrive element with transgenes expressing Cas9 with germline regulatory elementssds3,bgcn, andnup50. We only find inheritance bias through homing, even with the identicalnup50-Cas9 transgene. We propose that DNA repair outcomes may be more context dependent than anticipated and that other previously reported homing drives may, in fact, bias their inheritance through other mechanisms.
