Article Abstract

The insertion-deletion polymorphism of the serotonin transporter gene (SLC6A4) was studied using the polymerase chain reaction (PCR) in eight populations from the Volga-Ural region (the Bashkir, Chuvash, Tatar, Udmurt, Mari, Mordovian, and Komi populations and the population of Russians living in the Arkhangel's skii raion of Bashkortostan). For this polymorphic system, the pattern of distribution of main population parameters was established in the region studied. Depending on population ethnicity, specific trends were revealed in the pattern of frequencies of alleles and genotypes of gene SLC6A4.

Given the challenges of overcrowded coastal aquaculture spaces and insufficient production, utilizing saline-alkaline water areas represents a vital strategy to alleviate these bottlenecks. Spotted sea bass (Lateolabrax maculatus), with its formidable osmoregulatory capabilities, is an ideal candidate to develop a saline-alkaline tolerant strain. In our study, genotypic and phenotypic data from 287 L.

Given the presence of highly repetitive genomic regions such as subtelomeric regions, understanding human genomic evolution remains challenging. Recently, long-read sequencing technology has facilitated the identification of complex genetic variants, including structural variants (SVs), at the single-nucleotide level. Here, we resolved SVs and their underlying DNA damage-repair mechanisms in subtelomeric regions, which are among the most uncharted genomic regions.
