Background: Alpaca is a domestic South American camelid probably arising from the domestication of two wild camelids, the vicugna and the guanaco. Two phenotypes are described for alpaca, known as huacaya and suri. Huacaya fleece is characterized by compact, soft, and highly crimped fibers, while suri fleece is longer, straight, less crimped, and lustrous.

- - The study analyzed whole-genome sequencing data from 37 South American Camelids (alpaca, llama, vicugna, and guanaco) to understand their genetic relationships and identify loci under selection.
- - Results showed distinct genetic separation among the species, with notable genetic introgression from vicugna and llama into alpaca, while guanaco exhibited minimal admixture with the other species.
- - Specific Runs Of Homozygosity (ROHs) were identified, with alpaca having longer ROHs and shared loci that may indicate evolutionary adaptations, while each species revealed unique genetic markers associated with potential selection pressure.
In cashmere production studies, few trials have considered the guard hair features and their correlation with down fiber attributes. In this preliminary work, early observations on 158 one year old Chinese Alashan Left Banner White Cashmere goats were carried out. The aim was to describe the phenotypic correlation between the guard hair length and other fiber traits.

It has a complex structure with several promoters and alternative non-coding first exons that are transcribed into mRNAs with different 5'UTR. These mRNA isoforms regulate the temporal and spatial expression of the gene, producing diverse pigmentation patterns.
