The trans-complementing Gene Drive (tGD) is a 1-locus, 2 target site drive. The first target site corresponds to the Cas protein, the second to an effector gene and the gRNAs. There are two sets of gRNAs, because each target site may have different cutting/homing/resistance rates, and each sex can have different rates for all of those things. Additionally, the parent that you receive your Cas from dictates its efficiency. Therefor, this construct has 6 alleles at the first locus and 5 alleles at the second.
