Elena repeats in chicken IGS. Relationships between repeats in the Elena (EL) group. The figure was plotted using the maximum likelihood method. The numbers following the repeat names indicate the repeat ordinal position in the IGS, and the numbers following after a space—the IGS ordinal position in WAG137G4_utg0 contig. An expanded figure is attached in Additional file 4
