Peruvian alpacas represent 85% of the global population and are mainly bred for their fiber and adaptation to high-altitude Andean environments. Two distinct phenotypes exist: Huacaya and Suri. This study aimed to investigate the genetic population structure of alpacas (Vicugna pacos) using genotyping by sequencing (GBS), also known as restriction enzyme-reduced representation sequencing, and to evaluate its application as a breeding tool. We sampled 838 Huacaya and Suri alpacas of varying coat
