Evolution of gene families and chromosome between sika deer and red deer. A Sika deer and red deer gene families cluster result. B Increasing trend of all gene families and decreasing trend of core gene families as number of deer genomes increases. C Microsynteny of the chromosome-level genome of sika deer and red deer. Red deer chromosome 23 and chromosome 4 synteny with sika deer chromosome 1. D Circos plots showing genome collinearity between Cni-M and Cervus elaphus. E Circos plots showing genome collinearity between Cni-M and Cervus hanglu yarkandensis. F Circos plots showing genome collinearity between Cni-M and Cervus canadensi
