Topic:Lineage
Lineage in horses refers to the genetic heritage and ancestry that influence a horse's characteristics, performance, and breeding value. It encompasses the study of pedigrees, genetic markers, and inheritance patterns to understand traits passed from one generation to the next. Lineage analysis is utilized in breeding programs to enhance desirable traits such as speed, endurance, temperament, and conformation. This topic includes investigations into the genetic diversity within horse populations, the impact of selective breeding, and the identification of genetic disorders. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, findings, and implications of lineage studies in equine genetics and breeding strategies.
Population Genetic Analysis of the Estonian Native Horse Suggests Diverse and Distinct Genetics, Ancient Origin and Contribution from Unique Patrilines. The Estonian Native Horse (ENH) is a medium-size pony found mainly in the western islands of Estonia and is well-adapted to the harsh northern climate and poor pastures. The ancestry of the ENH is debated, including alleged claims about direct descendance from the extinct Tarpan. Here we conducted a detailed analysis of the genetic makeup and relationships of the ENH based on the genotypes of 15 autosomal short tandem repeats (STRs), 18 Y chromosomal single nucleotide polymorphisms (SNPs), mitochondrial D-loop sequence and lateral gait allele in DMRT3. The study encompassed 2890 horses of 61 b...
Genetic diversity and origin of the feral horses in Theodore Roosevelt National Park. Feral horses in Theodore Roosevelt National Park (TRNP) represent an iconic era of the North Dakota Badlands. Their uncertain history raises management questions regarding origins, genetic diversity, and long-term genetic viability. Hair samples with follicles were collected from 196 horses in the Park and used to sequence the control region of mitochondrial DNA (mtDNA) and to profile 12 autosomal short tandem repeat (STR) markers. Three mtDNA haplotypes found in the TRNP horses belonged to haplogroups L and B. The control region variation was low with haplotype diversity of 0.5271, nucleotide...
