Genetic variability in the Skyros pony and its relationship with other Greek and foreign horse breeds
Provedor de dados: 74
Autores: Bömcke,Elisabeth; Gengler,Nicolas; Cothran,E. Gus.
In Greece, seven native horse breeds have been identified so far. Among these, the Skyros pony is outstanding through having a distinct phenotype. In the present study, the aim was to assess genetic diversity in this breed, by using different types of genetic loci and available genealogical information. Its relationships with the other Greek, as well as foreign, domestic breeds were also investigated. Through microsatellite and pedigree analysis it appeared that the Skyros presented a similar level of genetic diversity to the other European breeds. Nevertheless, comparisons between DNA-based and pedigree-based results revealed that a loss of genetic diversity had probably already occurred before the beginning of breed registration. Tests indicated the...

Mitochondrial DNA D-loop sequence variation among 5 maternal lines of the Zemaitukai horse breed
Provedor de dados: 74
Autores: Cothran,E. Gus; Juras,Rytis; Macijauskiene,Vale.
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...

Genetics of the Pantaneiro horse of the Pantanal region of Brazil
Provedor de dados: 74
Autores: Cothran,E. Gus; Santos,Sandra Aparecida; Mazza,Maria Cristina Medeiros; Lear,Tery L.; Sereno,J. Robson Bezerra.
Genetic variation at seven red blood cell alloantigen, blood group loci and 10 biochemical genetic loci was examined in 102 Pantaneiro horses from the Pantanal region of Brazil and compared to that of other domestic horse breeds. Measures of both individual genic variation and populational genetic diversity within the Pantaneiro were near the average for domestic horse breeds. From the standpoint of genetic conservation there is no immediate concern for loss of variation within the Pantaneiro. Analysis of genetic relationship showed that the Pantaneiro was clearly of Iberian Peninsula descent and that it was most closely related to other Brazilian breeds.
