Article Synopsis
- The study analyzed the genetic makeup of Orenburg goats using SNP data from modern and historical samples, revealing that the genetic characteristics from older populations have persisted in current goats.
- Findings indicated low inbreeding rates and maintained genetic diversity, providing a basis for selective breeding and potential conservation strategies through gamete preservation.
Selective footprints and genes relevant to cold adaptation and other phenotypic traits are unscrambled in the genomes of divergently selected chicken breeds.

Article Synopsis
- The text discusses the impact of evolutionary and environmental factors on the genomes of various poultry breeds, particularly in relation to cold tolerance and performance traits.
- Using a specialized SNP chip, researchers genotyped four different chicken breeds and identified genomic regions indicative of selection for cold adaptation through multiple analysis methods.
- The study highlights several key candidate genes linked to cold tolerance and suggests that both genetic and epigenetic factors may play roles in how these breeds adapt to harsh climates, pointing to the need for more research on these mechanisms.
Comparison of genomic footprints in chicken breeds with different selection history is a powerful tool in elucidating genomic regions that have been targeted by recent and more ancient selection. In the present work, we aimed at examining and comparing the trajectories of artificial selection in the genomes of the native egg-type Russian White (RW) and meat-type White Cornish (WC) breeds. Combining three different statistics (top 0.

In our previous work using whole-genome single nucleotide polymorphism (SNP) analysis, we found that the population inhabiting Kharaulakh Ridge was genetically different from the other populations of Yakut subspecies to which it was usually referred. Here, our study was aimed at the clarification of taxonomic status of Kharaulakh snow sheep using mitochondrial cytochrome b gene.

- Native cattle breeds are valuable for agricultural adaptation and cultural heritage, holding genetic diversity crucial for responding to climate change challenges.
- The study focused on the unique evolutionary paths of northern Russian cattle breeds, finding that Kholmogory is typical taurine cattle, while Yakut cattle diverged about 5,000 years ago and adapted to extreme Arctic conditions.
- Genetic analysis indicated both breeds share common pathways for climate adaptation, but differ in specific genes affected, with Yakut cattle showing a unique mutation in the NRAP gene linked to adaptations in various hibernating mammals, hinting at convergent evolution.
Article Synopsis
- The Karachaev goat is a local breed native to the North-Caucasus region of Russia.
- The complete mitochondrial genome of this breed was analyzed, measuring 16,624 base pairs (bp) in length.
- The analysis revealed that this specific specimen belongs to haplogroup A.
