Phenotypic and genetic description of fibre traits in South American domestic camelids (llamas and alpacas)

Even though llamas and alpacas are multipurpose animals, fibre production remains the main trait from an international market point of view. The objectives of this review are to describe the phenotypic traits that determine fibre quality, and to identify the genetic mechanisms governing them. The fi...
