Synteny between date palm genetic map linkage group 18, coconut sequence markers and oil palm chromosome sequences. Similar to Figure 5 using coconut genetic map to compare to the oil palm. Coconut genetic map markers were mapped to scaffolds in the date palm genetic map. Linkage groups (LG) were colored by the most likely orthologous chromosome (chr) with orthology based on frequency of shared markers. Date palm LG1 is added for reference.
