Fig. 6From: Adaptive evolution characteristics of mitochondrial genomes in genus Aparapotamon (Brachyura, Potamidae) of freshwater crabsA Divergence time estimation of genus Aparapotamon.The digital numbers behind the branch indicated the estimated species divergence time (Ma: million years ago). The species sequenced in this study are marked by a star after the name. For A. gracilipedum: A (ON000286); B (OP526650); C (MZ350905). B The linear genome arrangements of 13 species in the genus Aparpatamon. The grey dotted frame indicates the region with great variety, including the specific arrangement of tRNA-Ile in group ABack to article page
