Chromosome sequencing

Luciobarbus brachycephalus represents a commercially valuable fish species in China, contributing significantly to regional aquaculture economies. High-density genetic linkage mapping coupled with quantitative trait locus analysis has emerged as a powerful approach for elucidating the genetic mechanism of complex traits in aquatic species. The present study aimed to construct a SNP based high-density linkage map using male parent, female parent, and gynogenetic full-sib progenies through whole genome resequencing strategy, and subsequently perform comprehensive QTL mapping of six economically important growth-related traits, in order to identify candidate genes underlying growth regulation in L. brachycephalus.
