TLDR The KRTAP36-1 gene affects wool quality in Chinese Tan lambs.

This study on 246 Chinese Tan lambs examined the KRTAP36-1 gene and its impact on wool traits, particularly mean fibre curvature (MFC) in fine wool fibres. Three alleles (A, B, and C) were identified, with allele C significantly associated with increased MFC in fine wool, but not in heterotypic hair fibres. The findings suggest that KRTAP36-1 influences wool characteristics, which could inform breeding strategies for improved wool quality. Further research is needed to explore the full range of KRTAP genes and their effects on wool and hair traits.
