Fig. 2From: Sex chromosome evolution in snakes inferred from divergence patterns of two gametologous genes and chromosome distribution of sex chromosome-linked repetitive sequencesComparison of partial nucleotide and amino acid sequences of CTNNB1 and WAC genes. Nucleotide and amino acid sequences are aligned between the homologs of CTNNB1 (a) and WAC (b) genes in five tetrapod species: E. quadrivirgata, A. carolinensis, G. gallus, H. sapiens and X. tropicalis. Numbers on the alignments indicate nucleotide positions from the translation initiation sites. Arrowheads in b indicate two predicted translational initiation sitesBack to article page
