Huitong Zhou, Lingrong Bai, Shaobin Li, Wenhao Li, Jiqing Wang, Jinzhong Tao, Jon G. H. Hickford

TLDR More research is needed to improve wool and cashmere quality through genetics.

The document reviews the genetic complexities and challenges in improving wool and cashmere fibre quality, focusing on the roles of keratin and keratin-associated protein (KAP) genes. Despite advancements in genetic research, the detection and characterization of these genes are limited due to the involvement of numerous genes with minor effects and the presence of extended SNP haplotypes. The review emphasizes the need for comprehensive genetic studies, improved methods, and expanded reference databases to better understand gene expression patterns and enhance fibre quality through selective breeding. Future research should prioritize gene identification, variation characterization, and expression analysis to advance genetic improvement strategies for wool and cashmere fibres.
