Topic:Genotyping
Genotyping in horses involves analyzing the genetic makeup of individual horses to identify specific genetic markers. This process aids in understanding genetic variations that may influence traits such as coat color, disease susceptibility, and performance capabilities. Genotyping can be used in breeding programs to select for desirable traits and manage genetic diversity within populations. Common methods for genotyping include single nucleotide polymorphism (SNP) analysis and microsatellite markers. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, applications, and implications of genotyping in equine genetics and breeding.
The American Quarter Horse: population structure and relationship to the thoroughbred. A breed known for its versatility, the American Quarter Horse (QH), is increasingly bred for performance in specific disciplines. The impact of selective breeding on the diversity and structure of the QH breed was evaluated using pedigree analysis and genome-wide SNP data from horses representing 6 performance groups (halter, western pleasure, reining, working cow, cutting, and racing). Genotype data (36 037 single nucleotide polymorphisms [SNPs]) from 36 Thoroughbreds were also evaluated with those from the 132 performing QHs to evaluate the Thoroughbred's influence on QH diversity.
