Control
Allodiploid GSF(female) x WM(male) Sterile sex ratio about 50:50

Pressure Shocked
Allotriploid GSF(female)^2 x WM(male) Sterile

Several hybrids I have made with WM have major viability issues. GSF have not such problems and often show some level of fertility, in at least one sex. WM and GSF not close kin. GSF more closely related to other Lepomis than WM. WM in my opinion should not be in Lepomis.
