Figure 2From: Toward understanding the genetic basis of adaptation to high-elevation life in poikilothermic species: A comparative transcriptomic analysis of two ranid frogs, Rana chensinensis and R. kukunorisDistribution of Ka and Ks values. Orthologous pairs with Ka/Ks ratio >1 are above the black line; pairs with Ka/Ks ratio between 0.5-1 are between the black and grey lines.Back to article page
