Dendrograms of birds using different gene lists related to fatness and obtained by different statistical methods. (A) 287 genes correlated to the fatness trait obtained by a classical approach. (B) 660 genes correlated to the fatness trait and/or differentially expressed obtained by classical approaches . (C) 688 genes correlated to the fatness trait obtained by FAMT method . Orange/blue bars indicate the 20 fattest/leanest animals respectively. Darkest bars correspond to the 10 extreme animals of the 2 fattest/leanest groups. Colorless bars correspond to the 5 intermediate chickens.
