Genes under positive selection in both N. furzeri and A. limnaeus. a Eight orthologs have at least one site under putative positive selection in both A. limnaeus and N. furzeri. One of these shared orthologs is hspa4, which was also found to be significantly increased in expression during anoxia in DII embryos and in post-DII embryos compared to DII controls. b Putative A. limnaeus positively selected sites of these eight orthologs occurs both within predicted domains and between them. Numbers on the X-axis refer to amino acid location. Red, selected site; Black, conserved domain predicted by InterProScan 5; Light blue, repeat domain
