One hundred and ninety five Pampa horses and a control group of 41 Paint Horses originated from herds located in different Brazilian regions were used to objective of evaluate the efficiency of the biochemical markers albumin (Al) and vitamin D binding protein (Gc) to identify the probable homozygous dominant for the tobiano coat color pattern in Pampa horses. It was not found any genotype AlBB and GcSS, indicating a possible break of the genetic linkage between these loci and the locus Tobiano, as well as the inefficacy of the biochemical test in the detection of the probable homozygous dominant for the tobiano color pattern in Pampa horses.
