Topic:mtDNA
Mitochondrial DNA (mtDNA) in horses refers to the genetic material found within the mitochondria, distinct from the nuclear DNA. It is maternally inherited and does not undergo recombination, making it a valuable tool for studying maternal lineage and population genetics in equine species. mtDNA analysis is used to trace evolutionary history, assess genetic diversity, and understand phylogenetic relationships among horse breeds. Variations in mtDNA sequences can provide insights into domestication patterns and historical migrations of horse populations. This page compiles peer-reviewed research studies and scholarly articles that explore the structure, function, and applications of mitochondrial DNA in equine genetic research.
Current genetic conservation of Chinese indigenous horses revealed with Y-chromosomal and mitochondrial DNA polymorphisms. To investigate the genetic diversity of Chinese indigenous horses and determine the genetic status of extant horse breeds, novel Y chromosomal microsatellite markers and known Y chromosomal SNPs and mtDNA loop sequences, were employed to study the genetic diversity levels of 13 Chinese indigenous horse populations and four introduced breeds. Sixteen Y-chromosomal microsatellite markers, including seven newly identified loci, were used in the genotyping. The results showed that 4 out of the 16 loci were highly polymorphic in Chinese indigenous horse populations, in which the polymorphisms of 3 ...
A new view on dam lines in Polish Arabian horses based on mtDNA analysis. Polish Arabian horses are one of the oldest and the most important Arab populations in the world. The Polish Arabian Stud Book and the Genealogical Charts by Skorkowski are the main sources of information on the ancestors of Polish Arabs. Both publications were viewed as credible sources of information until the 1990s when the data regarding one of the dam lines was questioned. The aim of the current study was to check the accuracy of the pedigree data of Polish dam lines using mtDNA analysis. The analyses of a 458 bp mtDNA D-loop fragment from representatives of 15 Polish Arabian dam lines re...
