Bruce and Shorty :

Help me understand your posts.

Shorty did they mean that a hybrid BG when looked at would look different if it was male vs. female ( I know 97% are male) or were they saying male BG x female GSF look different from female BG x male GSF. I know any particular HBG may look different from others because of the genetic line up of traits ( while 99 out of 100 may look the same the 100th may look different).

Bruce are you talking about a backcross of a HBG and a GSF? Do you have a pic. of that? See below for why I ask.

Abstract.�Attempts to backcross F1 male bluegill (Lepomis macrochirus) x green sunfish (Lepomis cyanellus) hybrids with females of each parental species were unsuccessful both in ponds and in the laboratory. In laboratory experiments, fertilization was accomplished but embryos failed to survive longer than 36 h. In ponds, nesting and courting activity were observed but successful reproduction did not occur. Additionally, 1,874 of 1,983 F1 hybrids examined (94.5%) were males.
