This function creates an inheritance cube to model an autosomal X-Shredder construct. This construct resides on an autosomal chromosome, and chops the X chromosome into many pieces during gametogenesis, destroying the X chromosome. Thus, males may only produce Y gametes and females can become sterile.
This drive has 2 loci:

  • Locus 1, the autosomal locus, has 3 alleles:

    • W: Wild-type allele

    • A: Attacking allele, contains the shredder construct

    • B: Broken attacking allele, shredder construct is defunct

  • Locus 2, the sex locus, has 3 alleles:

    • X: Wild-type X allele

    • R: X-allele resistant to cleavage

    • Y: Wild-type Y allele
