TLDR Certain genetic markers linked to wool quality in Rambouillet sheep were identified, which can guide better breeding choices.
The study on Rambouillet sheep identified significant genetic markers associated with wool quality traits, involving 313 ram lambs over three years. Key findings include SNPs on chromosomes 1, 2, 4, 15, and 19, explaining 6.13% to 8.25% of phenotypic variance. Notable markers include rs404487383 and rs406184307 on chromosome 1 for fiber diameter, and rs420943224 for clean fleece weight. Genes like ABCC8 and ULK4 were linked to skin wrinkle and face wool scores, respectively. These results suggest potential for genetic improvement in wool quality through marker-assisted selection, although further research is needed due to small sample sizes in some genotype categories.
