TABLE 3.

Chromosome position, TDT T_mHet statistic, degrees of freedom, and nominal P-values of chromosome-wise significant marker loci on SSC 1, SSC 9, and SSC 12

Marker	Chromosome	Position (cM)	TmHet	d.f.	P-value
SW1621	SSC 1	79.6	28.23	2	7 × 10−7a
SW1902	SSC 1	83.4	26.47	6	2 × 10−4a
S0081	SSC 9	77.0	20.47	5	9 × 10−4a
SW957	SSC 12	33.4	16.06	4	0.003b

Chromosome-wise significance level (α) is based on Bonferroni correction for testing multiple markers per chromosome.

^aChromosome-wise 1.0% significance threshold for SSC 1 (α = 7.1 × 10⁻⁴) and SSC 9 (α = 0.001).

^bChromosome-wise 5.0% significance threshold for SSC 12 (α = 0.007).
