Genes, Journal Year: 2023, Volume and Issue: 14(4), P. 808 - 808

Published: March 27, 2023

A large number of species and taxa have been studied for genetic polymorphism. Microsatellites known as hypervariable neutral molecular markers with the highest resolution power in comparison any other markers. However, discovery a new type marker—single nucleotide polymorphism (SNP) has put existing applications microsatellites to test. To ensure good studies populations individuals, microsatellite loci from 14 20 was often used, which corresponds about 200 independent alleles. Recently, these numbers tended be increased by application genomic sequencing expressed sequence tags (ESTs) choice most informative genotyping depends on aims research. Examples successful aquaculture, fisheries, conservation genetics SNPs are summarized this review. can considered superior such topics kinship parentage analysis cultured natural populations, assessment gynogenesis, androgenesis ploidization. coupled mapping QTL. will continue used research diversity stocks, also an economically advantageous technique.

Published: March 25, 2025

This chapter explores the applications of population genetics in genetic improvement and biodiversity conservation fish species. It traces evolution genetics, from earliest measurements variation at allozyme loci to current era genomics, highlighting technological advances that have revolutionized field. The emphasizes importance understanding both historical recent processes shaped patterns diversity, particularly face declines driven by anthropogenic activities climate change. Various molecular techniques used assess diversity are analyzed, including traditional markers such as allozymes DNA-based markers, amplified fragment length polymorphisms (AFLP), mitochondrial DNA (mtDNA), microsatellites. We discuss advantages disadvantages each method, emphasizing their application structure analysis, gene flow assessment, reproductive strategy studies. Additionally, addresses use these marker-assisted selection enhance productive traits commercially important primary objective is highlight how concepts, flow, drift, natural selection, can be applied improve Furthermore, for health sustainability aquatic populations, captivity wild, underscored.

Single-Nucleotide Polymorphism (SNP) array: an array of hope for genetic improvement of aquatic species and fisheries management

Deleted Journal, Journal Year: 2024, Volume and Issue: 1(1)

Published: Aug. 15, 2024

Abstract In recent years, significant progress in genomic technologies has revolutionized the field of aquaculture. These advancements have facilitated utilization DNA markers, particularly single nucleotide polymorphisms (SNPs), to enhance genetic characteristics aquatic species, leading overall improvements economically important traits. A SNP array or panel is a microarray designed with probes for locations, allowing identification specific alleles sample through hybridization fragmented DNA. arrays are known their efficiency, cost-effectiveness, and automation, making them high-throughput method genotyping. Thus, genome scale genotyping, aided by genotyping-by-sequencing (GBS), transformed aquaculture genetics. Recently, multi-species allow researchers study closely related species simultaneously, reducing costs enabling comparative genomics resource sharing. this paper, we reviewed global development key highlighted applications selection fisheries management. panels, commonly used genome-wide association studies (GWAS), leverage population linkage disequilibrium (LD) pinpoint variants associated production performance Using estimated breeding values (GEBVs) derived from data offers enhanced accuracy compared traditional pedigree based methods, especially when dealing challenging traits species. Overall, indicates that high-density panels offer consistent reliable tool genotyping across diverse populations. This technology demonstrated versatility being applied selection, characterization, genomics, QTL mapping The growing accumulation information abundance SNPs driven demand efficient cost effective techniques improvement programs
