  • Sex and genotypes expected from crosses of triploid females (st +/+ oy/st +) with non-PSR (st) and PSR males (st;PSR). For each category, a formula representing the expected brood proportion is also shown. The final column indicates the percentage expected for each category. These predictions use values of m = 40%, d = 40% and f = 67% (see appendix).
