Overview

Randomized trial demonstrates genetic loci linked to body measurement traits in Yili horses, suggesting implications for breeding.

Key Points

  • This study aims to identify genetic loci associated with body measurement traits in Yili horses using both conventional and machine learning-based GWAS methods.
  • Used a population of 255 adult Yili mares, including speed-type and meat-type individuals.
  • Conducted genome-wide association study using a mixed linear model and machine learning techniques, including Lasso regression and Random Forest.
  • Identified 238 mutation loci and annotated 277 candidate genes associated with body measurement traits.
  • Identified 238 mutation loci significantly associated with body measurement traits.
  • Annotated 277 candidate genes involved in biological processes such as muscle formation and energy metabolism.
  • Showed improved detection of genetic signals by integrating machine learning with conventional GWAS methods.
