| Summary: | Rock pigeon (Columba livia) is a member of the Columbidae family. This bird is distributed on all continents except Antarctica. Only domesticated forms Columba livia f. domestica are found in Lithuania, the true rock pigeon is found in southern Europe mainly in mountainous areas, where it is adapted to live. According to scientific sources, the rock pigeons are characterized by extremely low genetic diversity which is related to the carried selective breeding and the trait of rock pigeons to choose a partner regardless of kinship. A control region in the mitochondrial genome, also called the D–loop, is often chosen to study genetic diversity. The length and sequence of the control region varies between different bird species and individuals of the species, making it suitable for population genetics studies. In this study, 7 populations of rock pigeons from 3 regions are studied: Vilnius, Kėdainiai district, Ukmergės district and Kaunas from Lithuania, Vitonia and Pamplona from Spain and samples from Taiwan. Based on the identified sequences of the D-loop region of mitochondrial DNA, the population structure and the genetic diversity of the rock pigeons was assessed. The results of the study showed that individuals from different populations are not genetically differentiated. The samples were not divided into haplotype groups, they were characterized by low diversity of haplotypes and nucleotides. Principal coordinate analysis, AMOVA, and ΦST comparison revealed the separation of the Taiwan population from the other samples, but the presumed reason for this is the small Taiwan population. The study is important for the evaluation of the genetic diversity of rock pigeons. |
