ruct.
This construct resides on the Y chromosome, and chops the X chromosome into
many pieces during male spermatogenesis, destroying the X chromosome. Thus, males
only produce Y gametes.
This drive has 5 alleles at 1 locus:
X: Wild-type X chromosome
R: X chromosome resistant to destruction by the shredder construct
Y: Wild-type Y chromosome
A: Attacking Y chromosome, a Y chromosome with the shredder construct
B: Broken Y chromosome, a Y chromosome with a defunct shredder construct
