“…In Russia, the growing market demand for poultry products led, by 2020, to an elevation from 4 to 10% in the share of food products from non-traditional poultry species [2]. An increasing proportion of the world's egg and meat supply are provided from species of the Phasianidae (pheasant) family [3,4]. Hereby, quail breeding industry products are in special demand worldwide because of the palatability of quail eggs and meat, as well as the early onset of sexual maturity.…”

“…Hereby, quail breeding industry products are in special demand worldwide because of the palatability of quail eggs and meat, as well as the early onset of sexual maturity. Because of this, the establishment and growth of large quail farms mean that quail eggs and meat are becoming everyday products [3][4][5][6][7].…”

“…Domesticated Japanese quail are a common poultry type used for meat and eggs in Europe, Asia and throughout the world. Quails have been used in genetic research since 1940 [8] and, over time, they have become an increasingly important biological model for developmental, behavioral and biomedical studies [3,4]. Belonging to the same Phasianidae family as chickens, quails have a number of advantages as a research model.…”

Traces of long-term artificial selection can be detected in genomes of domesticated birds via whole-genome screening using single-nucleotide polymorphism (SNP) markers. This study thus examined putative genomic regions under selection that are relevant to the development history, divergence and phylogeny among Japanese quails of various breeds and utility types. We sampled 99 birds from eight breeds (11% of the global gene pool) of egg (Japanese, English White, English Black, Tuxedo and Manchurian Golden), meat (Texas White and Pharaoh) and dual-purpose (Estonian) types. The genotyping-by-sequencing analysis was performed for the first time in domestic quails, providing 62,935 SNPs. Using principal component analysis, Neighbor-Net and Admixture algorithms, the studied breeds were characterized according to their genomic architecture, ancestry and direction of selective breeding. Japanese and Pharaoh breeds had the smallest number and length of homozygous segments indicating a lower selective pressure. Tuxedo and Texas White breeds showed the highest values of these indicators and genomic inbreeding suggesting a greater homozygosity. We revealed evidence for the integration of genomic and performance data, and our findings are applicable for elucidating the history of creation and genomic variability in quail breeds that, in turn, will be useful for future breeding improvement strategies.

“…Currently, poultry farming is the most efficient branch of animal husbandry, and domestic chicken ( Gallus gallus ) is the most common type of poultry [ 1 ]. Many years of divergent selection have resulted in a considerable variety of chicken breeds and populations that differ in terms of phenotypic variation, utility type, performance, and unique genetic architecture (e.g., [ 2 , 3 , 4 , 5 ]).…”

Monitoring the genetic diversity of small populations is important with respect to conserving rare and valuable chicken breeds, as well as discovery and innovation in germplasm research and application. Restriction fragment length polymorphisms (RFLPs), the molecular markers that underlie multilocus DNA fingerprinting (MLDF), have historically been employed for this purpose, but over the past two decades, there has been an irreversible shift toward high-throughput single-nucleotide polymorphisms (SNPs). In this study, we conducted a comparative analysis of archived MLDF results and new data from whole-genome SNP genotyping (SNPg) among 18 divergently selected breeds representing a large sample of the world gene pool. As a result, we obtained data that fit the general concept of the phylogenetic distribution of the studied breeds and compared them with RFLP and SNP markers. RFLPs were found to be useful markers for retrospective assessment of changes in the genetic architecture and variability underlying the phenotypic variation in chicken populations, especially when samples from previous generations used for MLDF are unavailable for SNPg. These results can facilitate further research necessary to assess the possibility of extrapolating previous MLDF results to study the long-term dynamics of genetic diversity in various small chicken germplasm populations over time. In general, the whole-genome characterization of populations and breeds by multiple SNP loci will further form the basis for the development and implementation of genomic selection with the aim of effective use of the genetic potential of the domestic gene pool in the poultry industry.
