The study on Spanish Merino sheep focused on identifying genomic markers associated with quality wool traits, analyzing over 12,800 records and conducting genome-wide association studies (GWAS). Researchers identified 74 genetic variants across 70 genes linked to wool traits, with notable genes such as EDN2, COL18A1, LRP1B, FGF12, and ADAM17 associated with fiber characteristics and hair follicle development. The study involved 559 sheep, with 76 sequenced based on fiber diameter, and highlighted the potential to restore fine wool production through genetic selection, providing insights for future breeding programs to enhance wool quality in Spanish Merino sheep.
