Association analysis of SNP with growth traits in four cattle populations.

Breeds	Growth traits	Genotype (mean $\pm$ SE)			$P$ value
		CC	CT	TT
Qinchuan cattle, QC	hip width (cm)	–	$\mathrm{41.230}\pm \mathrm{0.669}$	$\mathrm{43.328}\pm \mathrm{0.479}$	0.016${}^{*}$
	rump length (cm)	–	$\mathrm{43.423}\pm \mathrm{0.487}$	$\mathrm{44.689}\pm \mathrm{0.349}$	0.049${}^{*}$
Pinan cattle, PN	hip width (cm)	${\mathrm{46.000}}^{\mathrm{b}}\pm \mathrm{1.528}$	${\mathrm{46.220}}^{\mathrm{b}}\pm \mathrm{0.625}$	${\mathrm{46.610}}^{\mathrm{a}}\pm \mathrm{0.472}$	0.046${}^{*}$
	rump length (cm)	${\mathrm{45.000}}^{\mathrm{a}}\pm \mathrm{0.260}$	${\mathrm{45.583}}^{\mathrm{a}}\pm \mathrm{0.540}$	${\mathrm{48.537}}^{\mathrm{a}}\pm \mathrm{0.481}$	0.025${}^{*}$
Jiaxian red cattle, JX	body length (cm)	–	$\mathrm{139.000}\pm \mathrm{1.801}$	$\mathrm{143.721}\pm \mathrm{1.285}$	0.047${}^{*}$
	rump length (cm)	–	$\mathrm{43.476}\pm \mathrm{1.190}$	$\mathrm{44.882}\pm \mathrm{0.751}$	0.037${}^{*}$
Xianan cattle, XN	body height (cm)	$\mathrm{137.000}\pm \mathrm{1.732}$	$\mathrm{135.688}\pm \mathrm{4.226}$	$\mathrm{134.263}\pm \mathrm{4.722}$	0.191
	cannon bone circumference (cm)	$\mathrm{19.667}\pm \mathrm{1.154}$	$\mathrm{19.372}\pm \mathrm{1.539}$	$\mathrm{18.912}\pm \mathrm{1.254}$	0.189

Values with different superscripts (a, b) within the same row differ significantly at ${}^{*}P<\mathrm{0.05}$.
