A new view on dam lines in Polish Arabian horses based on mtDNA analysis.
Abstract: 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 revealed 14 distinct haplotypes. The results were inconsistent with pedigree data in the case of two lines. A detailed analysis of the historical sources was performed to explain these discrepancies. Our study revealed that representatives of different lines shared the same haplotypes. We also noted a genetic identity between some lines founded by Polish mares of unknown origin and lines established by desert-bred mares.

This research studied the genetic pedigree of Polish Arabian horses using mitochondrial DNA (mtDNA) analysis. Discrepancies were found between the genetic evidence and traditional pedigree records for some dam lines – female ancestral lines – of these horses.
Research Objectives and Approaches
- The study sought to verify the pedigree accuracy of Polish Arabian horse dam lines. This was necessitated by questions raised about the reliability of traditional pedigree data that had been accepted until the 1990s.
- The researchers used mitochondrial DNA (mtDNA) analysis as their investigative tool. Mitochondrial DNA is passed from mother to offspring, making it an effective way to trace maternal (dam) lineages in species.
- The investigation analyzed a 458 base pair mtDNA D-loop fragment from representatives of 15 Polish Arabian dam lines, looking for variations or similarities that could help clarify their true ancestry.
Key Findings
- The analysis yielded 14 distinct haplotypes or unique sets of DNA variations that can be traced to a single female ancestor. These haplotypes are effectively the genetic “fingerprints” of specific dam lines.
- The genetic evidence did not align with the traditional pedigree data for two of the dam lines. This discrepancy called into question the accuracy of the historical records for these lines.
- An in-depth examination of historical documentation was undertaken to resolve these discrepancies. This additional step was crucial to corroborate or refute the genetic findings and shed light on the true origins of the dam lines in question.
Implications and Observations
- The researchers observed that different dam lines shared the same haplotypes. This suggests common maternal ancestry among these lines, contradicting traditional pedigree delineations.
- The research also drew an unexpected link between some dam lines founded by Polish mares of unknown origin, and those established by desert-bred mares. Such a correlation, backed by genetic evidence, challenges established historical narratives and opens up new lines of inquiry regarding the ancestry of these Polish Arabian horses.
