  1. The G+ and G- chickens were generated from the F2FL population produced from the 2 generation intercross between the founder Fat and Lean lines. The G- and G+ chickens correspond to the individual females exhibiting the lowest and the highest muscle glycogen content within the F2FL population. NS = non-significant.
