Fig. 4From: Gene annotation errors are common in the mammalian mitochondrial genomes databaseThe hypothetical process of gene rearrangement in the model of tandem duplication/random loss for “WANCY” region in mammals. a. A typical mammalian “W-A-N-C-Y” gene order. b. Tandem duplication and random loss. The black lines indicate the duplicated region and the red stars show the genes lost during the evolution of marsupials. c. A typical marsupial gene orderBack to article page
