Estimation of variance components and genetic parameters for litter size at birth (LSB) and litter size at weaning (LSW) in the Markhoz goats.

Trait	${\sigma }_a^2$	${\sigma }_{pe}^2$	${\sigma }_e^2$	h2(±SE)	$h_G^2$	R
LSB	0.0024	0.49e−7	0.1278	0.019 (±0.028)	0.011	0.018
LSW	0.82e−7	0.0140	0.2421	0.32e−6 (±0.14e−6)	0.21e−7	0.055

${\sigma }_a^2$, additive genetic variance; ${\sigma }_{pe}^2,$ permanent environmental variance; ${\sigma }_e^2,$ residual variance; h², whole population heritability; $h_G^2$, genomic heritability; R, repeatability.
