Figure 4From: Molecular evolution of the keratin associated protein gene family in mammals, role in the evolution of mammalian hairCorrelation between GC (Guanine and Cytosine) content and divergence between KRTAP genes. The synonymous substitution rates (dS) among paralogs within each subfamily and codon GC content (GC%) (A) and third codon GC content (GC3%) (B) of each subfamily is plotted. Dots and circles represent high cysteine KRTAP (HS) and high glycine-tyrosine KRTAP (HGT), respectively. The linear regression formulae for GC and dS are shown.Back to article page
