Genome-wide identification of candidate breed-specific markers and selection signatures in Kalmyk cattle

Background and Aim: Kalmyk cattle (KALMYK) represent an indigenous Russian beef breed with valuable adaptive and productive characteristics under harsh continental steppe conditions. However, previous genomic studies have involved relatively small populations, and candidate markers that distinguish KALMYK from both spe...

Comprehensive Identification and Description of Mitochondrial DNA Haplogroups and Sub-Haplogroups in Snow Sheep (Ovis nivicola) in Support of Their Evolutionary History and Conservation

Mitochondrial DNA is a powerful marker for reconstructing maternal lineages and phylogeographic history in wild species. The snow sheep (Ovis nivicola), a mountain ungulate endemic to Siberia and the Russian Far East, is characterized by strong geographic fragmentation and a complex taxonomic structure. A formal mitoch...

Study of Genetic Resistance to Scrapie in Sheep of the Gene Pool Herd of the Southern Meat Breed and in Their First Generation (F1) Crossbreeds with Katumskaya Breed by the Prion Protein Gene (PRNP)

Characteristics of genetic resistance to Maedi-Visna in sheep breeds raised in Russia

Relevance. Small Ruminant Lentiviruses (SRLVs), including the Visna-Maedi Virus (VMV) in sheep, induce chronic progressive inflammation primarily targeting the nervous system, lungs, mammary glands, and joints. These viruses exhibit significant genetic variability, leading to a lack of effective therapies or vaccine...
