The 670,000 SNP Affymetrix Equine HD array was designed after screening more than 2 million SNPs spanning the Equine genome. It provides optimal genomic coverage of known genetic diversity among domestic horse breeds, maximizing utility for research in equine genetics, including genome-wide association studies, high-resolution genetic mapping, Mendelian trait mapping, diversity analysis, and selection signature analysis.
The Array includes:
- Approximately 400,000 markers between population tag SNPs
- Approximately 200,000 markers within population tag SNPs
- Approximately 70,000 SNPs from the GeneSeek Genomic Profiler Equine70k chip
- Additional SNP density within the equine major histocompatibility complex
