Figure 1From: A RAD-based linkage map and comparative genomics in the gudgeons (genus Gnathopogon, Cyprinidae)A linkage map of the interspecific cross between Gnathopogon caerulescens and Gnathopogon elongatus . The bars on each linkage group represent mapped RAD-tag markers. The lengths of the linkage groups are based on Kosambi cM. A detailed map is presented in Additional file 2: Figure S1.Back to article page
