Performance of the sheep used in qRT-PCR.

	Small-tail group	Big-tail group	P -value
Traits	6	6
The weight of tail fat	0.572 ± 0.138	1.917 ± 0.138	<0.01
The relative weight of tail fat (body weight)	0.018 ± 0.002	0.036 ± 0.002	<0.01
The relative weight of tail fat (carcass weight)	0.034 ± 0.003	0.065 ± 0.003	<0.01

Vales for the phenotypic data are shown as the mean ± standard error (SE). P-value as calculated using a t-test.
