Rates and ratios of heterozygous and homozygous variants in each of the gorillas sampled.

<p>Rates of heterozygous (light blue) and homozygous (dark blue) variants were called from sequence alignments against the gorilla reference genome and expressed as percentage rates. Note Kamilah’s low rate of homozygous variants, due to her providing the DNA from which the reference genome was assembled. The corresponding hom/het ratios (ratios of homozygous to heterozygous variant rates) show that eastern lowland gorillas (black) have higher ratios than western lowland gorillas (red). Additional data for Mukisi and EB(JC) (Mukisi_PvuII and EB_JC_PvuII) were taken from a previously published study <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0065066#pone.0065066-Scally1" target="_blank">[3]</a>.
