yes...one of the most overused examples when it comes to genetics..i finally get to do fly labs this year...so what do i do..i
1. breed them
2. then sort them
3. breed them again

after my first breed...my second breeding was "delayed"...and at first i was like oh crap, my flies are either sterile or gay...

thank goodness its all good now...only a couple more hundred flies to count...!!!

i hope i havent brought any back with me to the house :P
