From: Genome-wide identification and analyses of the AHL gene family in cotton (Gossypium)
Distribution and gene duplications of GrAHL genes. The scale on the circle is in Megabases. Each colored bar represents a chromosome as indicated. Gene IDs are labeled on the basis of their positions on the chromosomes. AHL name in red indicated the singleton; AHL name in blue indicated the synteny or collinearity among chromosomes. The WGD or segmental duplication was linked by blue lines, gray lines in the background indicated the collinear blocks among different chromosomes
