Variance components and heritability estimates for cardiomyopathy syndrome (CMS) resistance in the two Atlantic salmon populations investigated in this study, StofnFiskur year-class 2017 (SF-17) and SalmoBreed year-class 2018 (SB-18).

Parameters	SF-17	SB-18
${\sigma }_g^2$ (se)	3.11 (0.63)	3.62 (0.80)
${\sigma }_c^2$ (se)	1.50 (1.13)	4.28 (1.75)
${\sigma }_e^2$ (se)	3.29 (0.54)	6.98 (0.98)
${\sigma }_P^2$ (se)	7.91 (0.65)	6.31 (0.94)
$h^2$ (se)	0.39 (0.07)	0.57 (0.12)

${\sigma }_g^2$: genetic variance; ${\sigma }_c^2$: common environmental variance; ${\sigma }_e^2$: residual variance; ${\sigma }_p^2$: phenotypic variance; $h^2$: heritability; se: standard error.
