December 1966 in “Textile Research Journal” Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.
February 2024 in “BMC genomics” This study identified a gene variant in the TRPV3 gene that may explain the suri alpaca phenotype, characterized by longer and less crimped fleece, suggesting this variant's involvement in the development of these hair characteristics compared to the huacaya phenotype.

January 2010 in “Animal” In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

November 2015 in “Gene” In this study, TGFβR I was more highly expressed in alpaca ear skin than in back skin, suggesting it may inhibit coat hair growth, with let-7b downregulating TGFβR I protein through transcriptional repression.

October 2023 in “Animals” This study explored the genetic basis of fiber diameter in alpacas, identifying candidate genomic regions including four significant areas on VPA6, VPA9, VPA29, and an unassigned scaffold, using whole genome association analysis and a custom SNP microarray.
