This is a X-linked, sex-specific version of a split CRISPR drive. At the X locus is the Cas9, inherited in a Mendelian fashion. At a second, unlinked, autosomal locus are the gRNAs. When the two loci occur together, the gRNAs drive, with potential damaged alleles, but the Cas9 remains Mendelian. Deposition in this cube is performed when both pieces come together in females. This drive has 2 loci:

  • "Locus" 1, sex chromosomes, has 3 alleles

    • X: Wild-type X chromosome

    • C: X-chromosome carrying a Cas9 construct

    • Y: Wild-type Y chromosome

  • Locus 2, autosomal locus, has 4 alleles:

    • W: Wild-type allele

    • G: gRNA allele

    • R: Functional or low-cost resistance allele

    • B: Non-functional or high-cost resistance allele
