“…It is an unfavourable phenomenon that threatens genetic diversity and causes a significant deterioration in the quality of alpaca fibre, which is considered a luxury material (Podbielska et al, 2021;Wheeler et al, 1995). It has been proven that, despite various breeding practices, alpacas and llamas have not yet divided genetically, proving the phenomenon of hybridisation identified based on STR markers (Echalar et al, 2020;Echalar and Barreta, 2022;Podbielska et al, 2021;Varas et al, 2020), mtDNA (Barreta et al, 2013;Kadwell et al, 2001;Maté et al, 2007Maté et al, , 2004Melo et al, 2012;Podbielska and Piórkowska, 2022;Stanley et al, 1994) or even the Y chromosome (Marín et al, 2017). Probably also important in this case is the fact that the hybridisation of alpacas with llamas influenced the genomes of both species (Wheeler, 2012).…”

Genotyping-by-sequencing (GBS) is an extremely useful, modern and relatively inexpensive approach to discovering high-quality single-nucleotide polymorphisms (SNPs), which seem to be the most promising markers for identifying hybrid individuals between different species, especially those that can create backcrosses. In addition, GBS could become an invaluable tool in finding backcrosses, even several generations back. Its potential for the use of restriction enzymes and species is almost unlimited. It can also be successfully applied to species for which a reference genome is not established. In this paper, we describe the GBS technique, its main advantages and disadvantages, and the research carried out using this method concerning interspecies hybridisation and the identification of fertile hybrids. We also present future approaches that could be of interest in the context of the GBS method.

“…There are over 70 nuclear microsatellites reported for the SAC [22][23][24][25][26][27][28][29] that can be potentially used for the genetic characterization of SAC populations-a first step in making conservation strategies. In Peru, most studies (some involving microsatellites) have been carried out in alpaca and vicuña populations [21,[30][31][32], whereas in llama populations these were either focused on studying their origin [29,33,34] or on analyzing quantitative parameters related to the physiology, production, growth, or fiber of the animal [35][36][37][38].…”

Llamas (Lama glama) are invaluable resources of Peru. Despite their importance, their population is decreasing. The Camelid Germplasm Bank—Quimsachata was created as a guardian of this South American camelid (SAC) species and established a bank of llamas from their two types, Ch’aku and Q’ara. However, these populations need to present high genetic diversity to be considered suitable conservation stocks. Thus, in the present study, 13 microsatellites specific for the SAC were used to assess the current genetic variability and differentiation of the llama population from the Bank. The global population showed high genetic diversity with a total of 157 different alleles, with an average of 12.08 alleles per microsatellite, an expected and observed heterozygosity of 0.758 and 0.707, respectively, and an average polymorphic information content (PIC) of 0.723. Although considered as two different breeds and managed separately, the genetic differentiation between Ch’aku and Q’ara was low (FST = 0.01). Accordingly, the gene flow value was high (Nm = 30.5). Overall, our results indicate the existence of high genetic variation among individuals, and thus, this llama population could be considered a suitable genetic stock for their conservation and for sustainability programs. Additionally, the 13 microsatellites can be used to study other Peruvian llama populations and monitor the genetic variability of llamas from the Camelid Germplasm Bank—Quimsachata.
