Table 2 Observed allele frequencies and 95 % confidence intervals for SNPs in the PPARG, CEBPA and RXRA genes in an Argentinean crossbred population (Angus-Hereford-Limousin). A: purebred Angus; H. purebred Hereford; ¾A: 75 % Angus steers; ¾ H: 75 % Hereford steers; ½AH: 50 % Angus -50 % Hereford steers; LX: Limousine crossbred steers. N: number of animals genotyped efficiently for that SNP per genetic group. SNP rs109613657 (PPARG) showed no variability
