Descripción
The Peruano de Paso (PP) horse is famous for its four-beat, distinctive gait known as “Paso”. In this breed, the percentage of chestnut horses (a recessive trait) has increased dramatically in recent decades, fostered by the genetic selection performed. This study aims to determine the genetic influence and relationship of this increase on key morphological traits. To this end, we characterised the PP population and estimated genetic parameters for 7 morphological traits using a phenotypic database of 1047 chestnut and non-chestnut individuals. Estimates for genetic trends indicate that selection towards chestnut coats had a negligible influence on the morphological traits studied. This selection is strongly associated with a reduction in genetic diversity among chestnuts, and some traits show early signs of inbreeding depression. To our knowledge, this is the first study on the genetic basis of morphology in the Peruano de Paso breed, and it suggests only a very weak connection between morphological traits and coat colour.
