So folks don't have to filter through all the muck in the other thread, I'll paste my opinion here.
I feel that under strictly controlled conditions it may be useful for exactly what has just been argued. Some knowedge of dominant vs. recessive and other genetic info may be gained. I absolutely do not feel hybrids (sp. or ssp.) should be distributed to the average hobbyist. Particularly creatures belonging within a genus of which so little is (yet) known like Pterinochilus.
