Middle Anatolian Merino Microarray Genotype Data

The study investigates the genetic architecture of fibre diameter (FD) and staple length (SL) in Middle Anatolian Merino sheep using multi-locus genome-wide association study (GWAS) approaches. Heritability and variability analyses revealed contrasting patterns: FD showed moderate heritability (h² = 0.461) with low variability (CV = 7.570%), while SL exhibited low heritability (h² = 0.191) but high variability (CV = 24.437%). Genetic correlations indicated moderate positive relationships between FD and certain growth traits (rG = 0.385–0.455, p
