RELAX tests for pervasive changes in strength of natural selection on hemoglobin genes in notothenioids.

Phylogenetic tree of Notothenioid species used in analyses and results of the HyPhy RELAX tests for pervasive changes in strength of natural selection on hemoglobin genes in the research article “Cold-driven hemoglobin evolution in Antarctic notothenioid fishes prior to hemoglobin gene loss in white-blooded icefishes” by Thomas Desvignes, Iliana Bista, Karina Herrera, Audrey Landes, John H. Postlethwait.
