“…Low nucleotide diversity in Gotland breed is consistent with the low autosomal genetic diversity found in this breed. High nucleotide diversity within Lithuanian horse breeds is consistent with the results obtained by blood typing and DNA typing (Juras et al, 2003). The Zemaitukai horse has high nucleotide and sequence diversity despite having experience recent bottleneck.…”

“…Haplotypes from the same breed frequently clustered in separate groups that included breeds of completely different horse breed types. This same pattern has been seen in other studies of horse mtDNA (Vila et al, 2001;Jansen et al, 2002), but are different from ones obtained using blood and protein typing data, were horse breeds clustered corresponding to their known ancestry (Juras et al, 2003). The lack of a pattern may be attributed the high rate of evolution in the control region, which may cause a site to mutate once, and then mutate later changing back to the original haplotype.…”

Genetic variation in Zemaitukai horses was investigated using mitochondrial DNA (mtDNA) sequencing. The study was performed on 421 bp of the mitochondrial DNA control region, which is known to be more variable than other sections of the mitochondrial genome. Samples from each of the remaining maternal family lines of Zemaitukai horses and three random samples for other Lithuanian (Lithuanian Heavy Draught, Zemaitukai large type) and ten European horse breeds were sequenced. Five distinct haplotypes were obtained for the five Zemaitukai maternal families supporting the pedigree data. The minimal difference between two different sequence haplotypes was 6 and the maximal 11 nucleotides in Zemaitukai horse breed. A total of 20 nucleotide differences compared to the reference sequence were found in Lithuanian horse breeds. Genetic cluster analysis did not shown any clear pattern of relationship among breeds of different type.

“…Within the past decade, microsatellites have become the most popular genetic marker and have been successfully applied to parentage and relatedness testing in horses (e.g., Bowling et al, 1997), and to investigations of inter-and intrabreed variability in domestic and feral horse populations (e.g., Canon et al, 2000;Bjornstad et al, 2000;Juras et al, 2003;Aberle et al, 2004;Solis et al, 2005;Luís et. al., 2006;Plante et al, 2007).…”

ABSTRACT. Various horse populations in the Americas have an origin in Spain; they are remnants of the first livestock introduced to the continent early in the colonial period (16th and 17th centuries). We evaluated genetic variability within the Venezuelan Criollo horse and its relationship with other horse breeds. We observed high levels of genetic diversity within the Criollo breed. Significant population differentiation was observed between all South American breeds. The Venezuelan Criollo horse showed high levels of genetic diversity, and from a conservation standpoint, there is no immediate danger of losing variation unless there is a large drop in population size.

“…Among the array of molecular markers, microsatellites are considered especially suitable for biodiversity evaluation, owing to their codominant inheritance, high heterozygosity, ease and reliability of scoring, ubiquitous presence throughout the ge-croatIan draught horSe: genetIc dIverSIty nome, and a high degree of polymorphism (Takezaki and Nei, 1996). Microsatellite analysis is now a widespread technique for the designated genetic variability (Bjørns-tad and Røed, 2001;Bjørnstad et al, 2003;Juras et al, 2003;Aberle et al, 2004;Krüger et al, 2005;Solis et al, 2005;Druml et al, 2007;Luis et al, 2007b). In this study, we analyzed three autochthonous coldblood horse breeds with the aim to ascertain the levels of genetic variability and estimate genetic distances between them.…”

The genetic variability for a sample of 107 animals from three autochthonous Croatian horse breeds was estimated using 20 microsatellites. The average number of alleles per locus (6.3) and proportion of heterozygosity (0.732) indicated a moderate variability. The expected heterozygosity was similar among all breeds and ranged between 0.724 in the Posavina horse, and 0.737 in the Croatian Coldblood and Murinsulaner horse. The inbreeding coefficient F IS was low and non-significant over the three populations. The genetic differentiation among the three populations was low (F ST =0.026), suggesting that only 2.6% of the total genetic variability was due to differences between the breeds, and 97% to individual differences. The results of pairwise genetic differentiation suggest that the Posavina horse and the Croatian Coldblood were the most closely related populations (F ST =0.016). These results are confirmed by Nei's genetic distances with the highest value observed between the Posavina horse and the Murinsulaner (0.082) and the lowest between the Posavina horse and the Croatian Coldblood (0.044). An assignment test correctly assigned 82% of individuals to the correct breed. Strategies for preserving the original native genes in the Croatian native horse breeds should be considered in order to prevent these breeds from becoming extinct and include them in the future breeding programmes.
