TLDR Key genes linked to wool quality in Spanish Merino sheep can improve fine wool production.

This study on Spanish Merino sheep aimed to characterize wool quality and identify genes linked to these traits. Analyzing over 12,800 records using the Australian OFDA 2000 system, researchers assessed parameters like fiber diameter and staple length. Genome-wide association studies identified 74 variants in 70 genes, with key genes such as EDN2, COL18A1, and LRP1B linked to fiber traits, and FGF12 and ADAM17 linked to staple length, all crucial for hair follicle growth. The findings highlight the potential to enhance fine wool production in this breed by focusing on these genetic markers.
