Fig. 1

Genomic organization of α-keratin genes in 16 mammalian species according to phylogenetic tree, genomic position and blast results. The α-keratin genes name was based on that of the human. Connecting lines indicate α-keratin genes on the same chromosome/genomic scaffold. Direction of the arrows of each α-keratin gene indicate the direction in the contig. Filled figures: intact genes; empty figures: pseudogenes; empty figures with a vertical line: incomplete genes. In addition, all genes are divided into different colors: flanking genes (green); hair keratins (blue); epithelial keratins (red); hair follicle-specific epithelial keratins (purple). The numbers show the. Ancestral states of gene family sizes for each node in the phylogenetic tree
