How to Identify a Jeju Horse
The Jeju horse is a breed of South Korean horse that is native to the island of Jeju. Its coat color and genetic diversity help identify it from other horses, and it is noted for its strength and fitness. Listed below are the most common types of the Jeju horse. To learn more, check out the following article. Also read about the breed’s parentage and individual identification. Here are some helpful tips for identifying a Jeju Horse.
Jeju Horse’s coat color
Among the many features that distinguish a Jeju Horse, the coat color is an important one. The Jeju Horse is a native of the island of Jeju, a Special Self-Governing Province of Korea. Despite their small size, the Jeju horse is sturdy and robust, able to cope with low temperatures and pasture life. They were once considered endangered and were nearly extinct. As transportation methods became more efficient, the Jeju horse was protected as a Natural Monument No. 1 in 1999.
In the study, the coat color of 376 registered Jeju horses was defined. One-third of these horses were white patched. Among these horses, ECA3-inversion and an EDNRB 2-bp nucleotide substitution were identified as the most significant factors in Tobiano, Overo, and Sabino coat color, respectively. The study also concluded that the coat color of Jeju horses is highly related to a polymorphism within the KIT gene, which affects their coat color.
Although the Jeju Horse’s coat is unique, its color ranges widely. The most common color is brown, followed by reddish-brown, gray, and black. Its fur is often stained, and some individuals have reddish-brown coats. The average Jeju horse is about 163 centimeters tall and stands at a height of around 340 centimeters. As a result of the diversity in their genome, the Jeju Horse can come in any color from white to black.
The Jeju Horse’s coat color is important, and is often used as a guide to determine which breed of the animal to purchase. The basic color of the Jeju Horse is chestnut, but there are also variations among different breeds, with different shades of brown, gray, or black patches on the legs and lower abdomen. Several types of the breed also display distinct markings on their faces. Some breeds have white faces and other unique markings.
The history of the Jeju horse is a fascinating one. The island’s ancient history is rooted in its rich horse breeding culture. In 1276, the Mongols captured more than thirty thousand Jeju horses from Jeju Island. The Jeju stallions were neutered to make them easier to ride. The mares were left on the island for breeding. The Sambyeolcho army later rebelled, and was forced to give up their horses.
Its genetic diversity
In this study, the genetic diversity of the Jeju Horse was studied using two genetic markers. In addition to the common haplotype, these markers were also used to identify individual genetic variants. The findings showed that genetic differentiation between Thoroughbred horses and Jeju horses was low. However, some genes were highly variable in both species. Among these, LEX050 and LEX063 showed high genetic diversity.
eqCD1a6 is the gene responsible for producing the protein. This protein contains three segments, including the transmembrane region and the cytoplasmic tail. The eqCD1a6 gene has six exons. There are 51 SNPs within each exon, while 275 SNPs were found in the rest of the gene. Most of these mutations were located in Exon 2 and Exon 3.
In addition to the haplotypes, a group of researchers studied the mitochondrial DNA of the Jeju horse. These sequences showed that the genetic diversity of the Jeju horse is relatively high, but it is not that unique. Genetic diversity in horse breeds is widely observed, and the Jeju horse is no exception. The chromosome number of the horse was determined from the published sequences of seven breeds, and genetic diversity analysis revealed that the Cheju horse is composed of 17 different types.
Although the PZ population was once over a million, it is now estimated at less than 2,000. However, a few of the JH horses have Mongolian admixture in their genomes, possibly from cross breeding with MH horses. Genetic diversity of the Jeju Horse can be confirmed by performing whole genome comparisons. The JH population is believed to be more than 2,000. So, the genetic diversity of the Jeju Horse is much more complex than previously thought.
The average Hexp level of the Jeju horse is 0.738, whereas that of the Mongolian horse is 0.801. Both the Jeju and Halla horses have mixed maternal lineages, which suggests that they are closely related species. This study indicates that Halla and Jeju are closely related. In addition, Halla horses are used for horse racing and meat production. As a result, genetic diversity of the Jeju horse is very high, but little research has been conducted to determine its exact composition.
Its parentage
You’ve probably heard about the term hybrid breed. It’s a cross between two different breeds, each with a unique set of traits. The question is, “What does this mean for me?”
Its individual identification
Individual identification of the Jeju Horse requires a thorough knowledge of the breed’s characteristics. Horses in the Jeju region are typically small to medium-sized with a blocky body and long torso. While originally used as draft and farm horses, the endurance of the Jeju horse has made it a popular choice for racing. Its thick hooves and lack of horseshoes make it a natural for the sport.
The genetics of the Jeju horse was studied using 13 microsatellite markers located on different autosomes. This analysis resulted in the identification of 138 different alleles. Among the 191 JNH samples, the mean heterozygosity and polymorphic information content ranged from 0.317 to 0.990. Moreover, the results showed that the jeju horse exhibits significant differences in the frequency of alleles.
To determine whether the Jeju horse is a single specimen, researchers compared the eqCD1A6 gene sequences. They were able to detect specific sequence signatures that distinguish the Jeju horse from other breeds. Most of the Jeju horse-specific SNPs were located in exons 2 and 3. Using NCBI blast, they aligned the AA sequences. Orange lines indicate 37 conservative AA substitution spots in the Jeju horse. The gene domains are boxed with annotations.
PETA’s investigation uncovered the cruelty of the Jeju horses. The animal protection act was allegedly violated by the horse owners, and police in Jeju opened an investigation. As a result, the Korea Racing Authority and South Korean ministry of agriculture have implemented a retirement program for racehorses. It was not until this revelation that the Jeju horse was saved. They now have a better chance of survival than ever before.
DNA samples from the Jeju horse were used to identify individuals. A digital PCR platform was used to analyze the gene’s sequence. For individual identification of the Jeju horse, a eqCD1a6 locus was amplified using the genetic marker. The PCR was performed with 10 ng gDNA and two x Lamp Taq PCR Master Mix. Positive droplets are expressed in green clusters.
