Variants in the chromosomal region of the myostatin gene and their association with lines, performance and body measurements of Quarter Horses

The objectives of this study were to evaluate differences between the racing and cutting lines of Quarter Horses in the allele frequencies of polymorphisms identified in the chromosomal region of the myostatin gene (MSTN, ECA18) and to analyze the association of polymorphisms in this chromosomal region with the estimated breeding values (EBVs) for racing performance, given by the maximum speed index (SImax), height at withers (HW), thoracic perimeter (TP) and body length (BL) in the racing line, and with EBVs for HW, TP and BL in the cutting line.
