动物遗传标记辅助选择研究及其应用

随着分子数量遗传学及其相关学科的发展，有关动物遗传标记辅助选择方面的研究也在不断深入，且已经在动物遗传改良中有了一些成功应用的示例。就如何综合利用表型、系谱和遗传标记信息进行育种值估计的统计学方法研究方面，目前已基本形成了较为完善的统计学方法。同时，在标记辅助选择相对效率及其影响因素，以及标记辅助选择实施方案的研究上也取得了不少喜人的成果。本文综述了动物遗传标记辅助选择研究的一些进展，并对标记辅助选择在动物遗传改良中应用的有关问题进行了讨论。 Abstract:With the development of molecular and quantitative genetics and its related subjects,it made a great progress on the research about animal genetic marker-assisted selection (MAS).There were also some successful examples on the application of MAS to animal genetic improvement.The statistical method which using phenotypic,pedigree and genetic marker information to predict individual breeding values has already been developed.Many achievements were obtained from the researches,which carried on MAS relative efficiency and its affecting factors and selection schemes.The present paper reviewed some progresses of MAS research and discussed some problems about MAS application to animal breeding.

Research and Application of Animal Genetic Marker-assisted Selection

With the development of molecular and quantitative genetics and its related subjects,it made a great progress on the research about animal genetic marker-assisted selection (MAS).There were also some successful examples on the application of MAS to animal genetic improvement.The statistical method which using phenotypic,pedigree and genetic marker information to predict individual breeding values has already been developed.Many achievements were obtained from the researches,which carried on MAS relative efficiency and its affecting factors and selection schemes.The present paper reviewed some progresses of MAS research and discussed some problems about MAS application to animal breeding.
