From: Triploid Atlantic salmon are physiologically disadvantaged at larger body sizes

The oxygen extraction coefficient (α) at Pcrit and MMR in larger diploid and triploid Atlantic salmon. Columns in (A) are mean ± s.e.m and the asterisk indicate a significant difference between metabolic rate traits while different letters indicate a significant difference between ploidies within a metabolic rate trait (two-way ANOVA and Hold-Sidak test, P < 0.05) (n = 15). Panel (B) depicts individual α values versus PO2, showing that α decrease in hypoxia and overall is lower in the triploid group.
