I have four fold balancer stock CyO/Pm ; CxD/TM6b and there is some
recombination in this stock. So for example you find CyO flies with brown
ies and Plum-balancer with red ies. And you always find some TM6b flies
without Tubby. If FM7 is part of multiple balancer system you can«t trust
for any of the FM7 markers.
