Figure 1.—

Alignment of the 80 variable amino acid residues within SRY in 36 species of Felidae. Taxa are organized by recognized felid lineage (O'Brien and Johnson 2005; Johnson et al. 2006). The shaded area defines variable sites within the conserved HMG box. If these alignments are corrected for ocelot and clouded leopard (see text), the total number of variable sites is reduced from 80 to 61. Underlined species have indels within SRY. Asterisk denotes stop codon. Dash refers to insertion/deletion event.
