Abstract
|
|
|
|
Halla horse is crossbreed between Jeju and Thoroughbred horses and is used for riding, racing and meat production. Thus, molecular genetic studies are needed to establish and preserve the industrially valuable Halla horses. This study aimed to analyses the genetic diversity and population structure through 12 microsatellite (MS) markers for Halla and putatively related 3 breeds (Jeju, Mongolian and Thoroughbred horses). On average, the number of alleles, observed heterozygosity (Hobs), expected heterozygosity (Hexp), and polymorphic information content (PIC) among all horses were 10, 0.767, 0.799, and 0.771, respectively. Neighbor-joining tree and STRUCTURE analysis showed that Halla horses were between Thoroughbred and Jeju horses, tend to more influenced by Thoroughbred horses. Therefore, these results could be considered for use as the basic genetic breed relationships resource among the horse breeds (Jeju, Mongolian, and Thoroughbred horses) related to the origins of the Halla horse.
