Abstract Recent molecular tools and technologies have marked the discovery of the origin and domestication processes of a wide variety of species, using either genomic or mitochondrial molecular markers to provide input for selection programs, as well as the management and conservation of animal breeds. This study aimed to analyze genes of mitochondrial DNA of the following sheep (Ovis aries) breeds: Pantaneira, Bergamácia, Dorper, White Dorper, Ile de France and Hampshire Down, to obtain their population genetic parameters and investigate the origin of these sheep populations reared in the State of Mato Grosso do Sul. The analysis of mitochondrial DNA allowed to infer their phylogenetic relationships and revealed significant differences among them when compared with each other and with sequences obtained from GenBank. Through the formation of haplotypes, it was noted that the Pantaneira breed served as the maternal basis for the formation of the other breeds reared in the region, and it was possible to suggest a European origin for the sheep populations studied.

归化品种作为在热带高原地区形成外来绵羊（Ovis aries）品种基础的重要性

摘要 最近的分子工具和技术标志着对多种物种起源和驯化过程的发现，使用基因组或线粒体分子标记为选择程序以及动物品种的管理和保护提供输入。本研究旨在分析以下绵羊（Ovis aries）品种的线粒体 DNA 基因：Pantaneira、Bergamácia、Dorper、White Dorper、Ile de France 和 Hampshire Down，以获得它们的种群遗传参数并调查这些绵羊种群的起源在南马托格罗索州。线粒体 DNA 的分析允许推断它们的系统发育关系，并揭示它们之间的显着差异，当它们相互比较以及与从 GenBank 获得的序列进行比较时。
