Genetic diversity and relationships of Portuguese and other horse breeds based on protein and microsatellite loci variation.
Abstract: There are three native Portuguese horse breeds: Lusitano, Sorraia and Garrano. This study compares diversity patterns of 17 protein and 12 microsatellite markers in these three as well as 30 other breeds to infer relationships among the breeds and to compare levels of polymorphism of these breeds for use in conservation efforts. The Garrano and the Lusitano showed a high level of genetic diversity, similar to that observed for most of the other analysed breeds, while the Sorraia and Friesian breeds showed low levels of variation for both genetic marker types. The combined protein and microsatellite data produced a tree that fit historical records well and with greater confidence levels than those for either data set alone. The combined genetic diversity and relationship information provides important baseline data for future breed conservation efforts, especially for a critically endangered breed such as the Sorraia.

This research article focuses on the genetic diversity and relationships among Portuguese horse breeds and other breeds. It explores how certain markers can indicate the level of polymorphism in breeds, which can be instrumental in conservation work.
Overview of the Research
- The research’s core propose was to study the genetic diversity and relations among three native Portuguese horse breeds: Lusitano, Sorraia and Garrano.
- It compared the diversity patterns of 17 protein and 12 microsatellite markers in the three Portuguese breeds along with 30 other breeds.
- The aim was to infer relationships among the breeds and to compare levels of polymorphism (the occurrence of different forms among the members of a population) in these breeds.
Key Findings
- Among the Portuguese horse breeds, the Garrano and the Lusitano showed a high degree of genetic diversity, similar to what was observed for most other analyzed breeds.
- On the contrary, the Sorraia and Friesian breeds demonstrated low levels of variation for both types of genetic markers (protein and microsatellite).
- By combining protein and microsatellite data, it produced a classification tree that confidently matched historical records.
- This technique of data fusion provided more reliable information than analyzing either data set individually.
Significance and Applications
- This research provides a foundation for future acknowledgment of breed conservation efforts.
- The information about genetic diversity and relationship is particularly critical for endangered breeds like Sorraia.
- Understanding polymorphism levels in these breeds could assist in devising effective strategies to protect and preserve them.
- Moreover, this study underscores the utility of employing multiple types of genetic markers in analyzing genetic diversity and relationships among breeds.
