Signatures of selection in the indel-containing coding sequences from human to primate genome comparisons
(2013)
Gene sequences are relatively conserved, and usually show few differences in comparisons between closely related species, such as between humans and non- human primates. In this study, we focused on >10 bp insertions and ...
