Introduction. The article presents the results of the analysis of mitochondrial DNA and Y-chromosome samples obtained from the representatives of Sarmatian populations from the Lower Volga region belonging to all stages of the culture. Methods and materials. The authors have screened samples from 202 individuals representing three cultural and chronological Sarmatian groups (Early Sarmatian, Middle Sarmatian and Late Sarmatian cultures). As a result, the researchers have determined the structure and phylogenetic position of 62 mitochondrial DNA samples and 12 Y-chromosome samples, carried out a comprehensive analysis of the results. The authors have interpreted the obtained results in terms of the formation of the Sarmatian genetic composition and their genetic relationships. Results and discussion. The paper shows that the Sarmatian mitochondrial DNA pool is characterized by a high level of diversity, which is also typical for other Early Iron Age nomadic groups. The mitochondrial DNA lineages of Western Eurasian origin dominate in the Sarmatian gene pool, while lineages of Eastern Eurasian haplogroups cover less than 13% of the total sample. Data on both genetic markers suggests that the formation of the main features of the Sarmatian gene pool could be alternatively influenced by populations from more eastern regions, genetically more related to the Andronovo historical and cultural community, which is consistent with the data of physical paleoanthropology, or autochthonous populations of the Lower Volga and adjacent regions. The mitochondrial DNA data indicates a significant genetic influence of the populations from more southern regions of the Eurasian steppe belt on the Sarmatian gene pool. In addition, the authors show the presence of Eastern Eurasian components in the gene pools of all chronological Sarmatian groups, which may indicate the genetic influence of early nomads from eastern regions of the Eurasian steppe belt. The exact time of the appearance of these eastern genetic components in the Lower Volga region remains unclear. At the same time, the authors did not find the signs of an increase in the role of eastern components during the transition from the Early to Middle and to Late stages of the Sarmatian culture, which could be expected based on the data of archaeology and physical anthropology. Prospects. Prospects for a more detailed reconstruction of the Sarmatian genetic history in the Lower Volga region are associated with the further development of the diachronic model, including the accumulation of more mitochondrial DNA and Y-chromosome data for the population of each stage of the Sarmatian culture, the involvement of groups preceding the Sarmatians in the region in the study and the analysis of additional markers of nuclear DNA.

The objective of this work was to characterize Pantaneiro cattle genetically through its paternal ancestry by the morphology of the Y chromosome, whether submetacentric or acrocentric, as well as to identify the maternal ancestry through mitochondrial DNA. The karyotype and mitochondrial DNA of 12 bulls of Pantaneiro breed were analyzed. The Y chromosome was analyzed in lymphocyte metaphases and the mitochondrial DNA by diagnosing its haplotype (Bos taurus and Bos indicus). Among Pantaneiro animals analyzed three had a taurine (submetacentric) Y and nine had a zebuine (acrocentric) Y chromosome, suggesting breed contamination by Zebu cattle, once Pantaneiro is considered to be of European origin. The mitochondrial DNA was exclusively of taurine origin, indicating that the participation of zebuines in the formation of the breed occurred entirely through the paternal line.

En este estudio se analizan dos fragmentos del gen de la citocromo c oxidasa subunidad I (COX1) del ADN mitocondrial de 61 individuos del género Rhynchophorus colectados en la Región de Murcia a fin de determinar su procedencia. El análisis filogenético del fragmento 1 de las muestras de la Región de Murcia conjuntamente con las secuencias disponibles en GenBank indica que los individuos corresponden a la especie Rhynchophorus ferrugineus.Las secuencias de Murcia se colapsan en un único haplotipo (H8 mediterráneo) que aparece dentro del clado de R. ferrugineus. De los análisis filogeográficos se infiere que el origen de los individuos de Murcia es Egipto. Adicionalmente, se examinó una región contigua del COX1 (fragmento 2) en la que las secuencias se colapsaron en dos haplotipos. In this research two fragments of the cytochrome c oxidase subunit I (COX1) gene of the mitochondrial DNA were analyzed in 61 individuals of the genus Rhynchophorus collected in the Region of Murcia with the aim of determining their origin. Phylogenetic analysis of fragment 1 of the samples collected in the Region of Murcia together with the available sequences in GenBank, indicated that these individuals correspond to the species R. ferrugineus. Sequences from Murcia collapsed into the H8 Mediterranean haplotype, which cluster into the R. ferrugineus clade. Phylogeographic analysis shows that the origin of the individuals collected in the Region of Murcia is Egypt. Additionally, a contiguous fragment of COX1 (fragment 2) was analyzed and the sequences collapsed into two haplotypes.

Abstract Background According to history, in the pre-Hispanic period, during the conquest and Inka expansion in Ecuador, many Andean families of the Cañar region would have been displaced to several places of Tawantinsuyu, including Kañaris, a Quechua-speaking community located at the highlands of the Province of Ferreñafe, Lambayeque (Peru). Other families were probably taken from the Central Andes to a place close to Kañaris, named Inkawasi. Evidence of this migration comes from the presence near the Kañaris–Inkawasi communities of a village, a former Inka camp, which persists until the present day. This scenario could explain these toponyms, but it is still controversial. To clarify this historical question, the study presented here focused on the inference of the genetic relationship between ‘Cañaris’ populations, particularly of Cañar and Ferreñafe, compared to other highland populations. We analysed native patrilineal Y chromosome haplotypes composed of 15 short tandem repeats, a set of SNPs, and maternal mitochondrial DNA haplotypes of control region sequences. Results After the genetic comparisons of local populations—three from Ecuador and seven from Peru—, Y chromosome analyses (n = 376) indicated that individuals from the Cañar region do not share Y haplotypes with the Kañaris, or even with those of the Inkawasi. However, some Y haplotypes of Ecuadorian ‘Cañaris’ were associated with haplotypes of the Peruvian populations of Cajamarca, Chivay (Arequipa), Cusco and Lake Titicaca, an observation that is congruent with colonial records. Within the Kañaris and Inkawasi communities there are at least five clans in which several individuals share haplotypes, indicating that they have recent common ancestors. Despite their relative isolation, most individuals of both communities are related to those of the Cajamarca and Chachapoyas in Peru, consistent with the spoken Quechua and their geographic proximity. With respect to mitochondrial DNA haplotypes (n = 379), with the exception of a shared haplotype of the D1 lineage between the Cañar and Kañaris, there are no genetic affinities. Conclusion Although there is no close genetic relationship between the Peruvian Kañaris (including Inkawasi) and Ecuadorian Cañar populations, our results showed some congruence with historical records.
