Genomic Signatures of Positive Selection in Human Populations of the , , , and Gene Variants Related to the Regulation of Psychoemotional Response.

The neurobiological systems of maintenance and control of behavioral responses result from natural selection. We have analyzed the selection signatures for single nucleotide variants (SNV) of the genes of oxytocin (, ) and vasopressin (, , ) systems, which are associated with the regulation of social and emotional behavior in distinct populations. The analysis was performed using original WGS (whole genome sequencing) data on Eastern Slavs (SlEast), as well as publicly available data from the 1000 Genomes Project on GBR, FIN, IBR, PUR, BEB, CHB, and ACB populations (the latter were taken as reference).

Assessing the Effect of SNPs on Litter Traits in Pigs.

The reproductive ability of sows is the principle of continuous and efficient production, based on such traits as the number of piglets, the total number of parities, and the period of economic use. Currently, SNPs associated with the TNB and NBA are presented in the PigQTLdb. The aim of this work was the assessment of the SNP effects on the litter traits in Large White (LW,  = 502) and Landrace (LN,  = 432) sow breeds in a farm in Russia.

Polymorphism of gene in three sheep breeds grown in the steppe zone of the Russian Federation.

Objective: This study aims to investigate the callipyge gene () polymorphism in sheep of Edilbay, Volgograd, and Kalmyk breeds.

Materials And Methods: The analysis was performed by the polymerase chain reaction-restriction fragment length polymorphisms method. The objects of the study were Edilbay fat-tailed sheep ( = 500) at the breeding plant Volgograd-Edilbay (Volgograd region), Volgograd fine-wool sheep ( = 500) at the breeding plant Romashkovskiy (Volgograd region), and Kalmyk fat-tailed sheep ( = 500) at the breeding plant Kirovsky (the Republic of Kalmykia, Yashkul rayon).
