1IMF: intramuscular fat content; SFA, MUFA, PUFA: saturated, monounsaturated, and polyunsaturated fatty acids; C18:1: oleic acid; C18:0: stearic acid. Determined on muscle gluteus medius.
236k: using the 36,432 SNPs in the chip; SCD: using only g.2228T>C from the SCD promoter; LEPR: using only c.1987C>T from exon 14 of the LEPR gene; SCD+LEPR: using the two SNPs at the SCD and LEPR loci; 36k−SCD−LEPR: all SNPs except the SSC14 at 120–124 Mb (SCD) and SSC6 at 135–137 Mb (LEPR) extended regions.
