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.
A study for genomic variation that may reflect putative selective signaling and be associated with economically important traits is instrumental for obtaining information about demographic and selection history in domestic animal species and populations. A rich variety of the Russian chicken gene pool breeds warrants a further detailed study. Specifically, their genomic features can derive implications from their genome architecture and selective footprints for their subsequent breeding and practical efficient exploitation.

- 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.

- The study aimed to assess genetic diversity in the White Fulani cattle breed by identifying DNA markers using microsatellite analysis.
- A total of 41 cattle samples were collected and analyzed, revealing a high level of heterozygosity of at least 70% and a diverse range of genetic alleles.
- The findings suggest that White Fulani cattle have significant genetic variation, which can be useful for conservation and the sustainable management of cattle genetic resources in Nigeria.
Article Synopsis
- The study investigates the population structure and origins of nine Russian cattle breeds, linking them to various historical and cultural influences in Russia.
- Genotyping using SNP analysis shows similar genetic diversity in eight breeds, with Yakut being notably different and identified as having unique Turano-Mongolian ancestry.
- The research concludes that some Russian breeds maintain a more authentic genetic profile with less introgression from foreign breeds, while others display transboundary European ancestry from well-known breeds like Holstein and Brown Swiss.
Article Synopsis
- * Researchers expressed the seh gene to produce a recombinant SEH toxin and developed specific monoclonal antibodies (mAbs) that do not cross-react with other staphylococcal enterotoxins.
- * A sandwich enzyme immunoassay method was established for detecting SEH, proving effective in both liquid food products and blood serum, with the highest extraction efficiency found in non-liquid foods at a pH of 4.0-4.5.
Article Synopsis
- * A small percentage of these SNPs were polymorphic, indicating low genetic variation, with 5.3% for bovines and 2.03% for ovines.
- * Despite varying distributions of SNPs across chromosomes, the results suggest that bovine and ovine SNP chips are effective tools for conducting whole-genome analysis in reindeer.
