Meat quality is of economic importance in farm animals. It is controlled by multigenes and the environment. During the past few decades, advances in molecular genetics have led to the identification of genes, or markers associated with genes, that affect meat quality. Work on sequencing farm animal genomes will help us to understand how genes function in various organisms and might be applied in the field to study the molecular control of meat quality. Candidate gene and genome scans are two main strategies to identify loci associated with the trait of meat quality. Several genes that influence meat quality have already been, or are close to being, identified. Some of them have been applied to the breeding of farm animals by marker-assisted selection. This will accelerate cumulative and permanent genetic improvement of herds.
肉质对家畜具有经济重要性。它受多基因和环境控制。在过去几十年中，分子遗传学的进展已导致鉴定出影响肉质的基因或与基因相关的标记。家畜基因组测序工作将帮助我们了解基因在各种生物体中的功能，并可能在该领域应用于研究肉质的分子控制。候选基因扫描和基因组扫描是鉴定与肉质性状相关位点的两种主要策略。几个影响肉质的基因已经或即将被鉴定出来。其中一些已通过标记辅助选择应用于家畜育种。这将加速畜群的累积和永久性遗传改良。
