Abstract
Originating in Thailand, the Thai Ridgeback dog is known for its unique fur ridge that grows in the opposite direction along its back. Selective breeding and a limited populations in Thailand have led to significant close inbreeding among related individuals. The current Thai Ridgeback population is assumed to have experienced a loss of genetic diversity and bottleneck events. Furthermore, studies on the genetic diversity and structure of Thai Ridgeback dogs are limited. Therefore, the aim of this study was to assess the genetic diversity in Thai Ridgeback dogs. Microsatellite genotyping and mitochondrial DNA D-loop sequences were used to assess genetic diversity in 105 Thai Ridgeback dogs from various farms throughout Thailand. Significant genetic diversity and minimal inbreeding were observed in the current Thai Ridgeback population. Signs of bottlenecks were not observed because the exchange of genetic material among Thai Ridgeback owners effectively preserved the genetic diversity. Moreover, the genetic parameters in this study supported owner-to-owner exchanges animals for mating programs. To sustain the genetic diversity of Thai Ridgeback dogs, the use of genetic parameters to manage genetic closeness while preserving breed characteristics is essential. These data are crucial for ensuring demographic stability, which is pivotal for long-term conservation and effective population management.
泰国脊背犬原产于泰国，因其背部独特的反向生长的毛脊而闻名。在泰国，选择性繁殖和有限的种群数量导致近亲繁殖现象严重。目前的泰国脊背犬种群被认为经历了遗传多样性丧失和瓶颈事件。此外，有关泰国脊背犬遗传多样性和结构的研究也很有限。因此，本研究旨在评估泰国脊背犬的遗传多样性。研究人员使用微卫星基因分型和线粒体 DNA D 环序列评估了来自泰国不同农场的 105 只泰脊背犬的遗传多样性。在目前的泰国脊背犬种群中观察到了显著的遗传多样性和极少的近亲繁殖。由于泰国脊背犬饲养者之间的遗传物质交换有效地保持了遗传多样性，因此没有观察到瓶颈的迹象。此外，本研究中的遗传参数还支持饲主与饲主之间交换动物用于交配计划。为了保持泰脊背犬的遗传多样性，在保持品种特征的同时，利用遗传参数来管理遗传亲缘关系是至关重要的。这些数据对于确保人口稳定性至关重要，而人口稳定性是长期保护和有效种群管理的关键。
期刊介绍：
Biochemical Genetics welcomes original manuscripts that address and test clear scientific hypotheses, are directed to a broad scientific audience, and clearly contribute to the advancement of the field through the use of sound sampling or experimental design, reliable analytical methodologies and robust statistical analyses.
Although studies focusing on particular regions and target organisms are welcome, it is not the journal’s goal to publish essentially descriptive studies that provide results with narrow applicability, or are based on very small samples or pseudoreplication.
Rather, Biochemical Genetics welcomes review articles that go beyond summarizing previous publications and create added value through the systematic analysis and critique of the current state of knowledge or by conducting meta-analyses.
Methodological articles are also within the scope of Biological Genetics, particularly when new laboratory techniques or computational approaches are fully described and thoroughly compared with the existing benchmark methods.
Biochemical Genetics welcomes articles on the following topics: Genomics; Proteomics; Population genetics; Phylogenetics; Metagenomics; Microbial genetics; Genetics and evolution of wild and cultivated plants; Animal genetics and evolution; Human genetics and evolution; Genetic disorders; Genetic markers of diseases; Gene technology and therapy; Experimental and analytical methods; Statistical and computational methods.
