This study will compare genetic diversity in Angus cattle using alleles that affect traits of economic importance and microsatellite markers, which are not under selection. Three populations of Angus cattle will be compared: Canadian Angus cows, Canadian Angus bulls, and elite ET calves from 10 countries including Canada. The six genes chosen for study are based on recently discovered DNA tests that are being implemented in commercial settings. The 20 microsatellite markers are a set selected specifically to monitor genetic diversity among breeds and over time by the Canadian Animal Genetic Resources Program. This information should be useful to the Canadian Angus Association to assess the level of diversity and of favorable alleles in their cattle relative to other major countries involved in Angus cattle breeding.

本研究将使用影响经济重要性性状的等位基因和未选择的微卫星标记来比较安格斯牛的遗传多样性。将比较三个安格斯牛群体：加拿大安格斯奶牛、加拿大安格斯公牛和来自包括加拿大在内的 10 个国家的精英 ET 小牛。选择用于研究的六个基因是基于最近发现的在商业环境中实施的 DNA 测试。这 20 个微卫星标记是加拿大动物遗传资源计划专门选择的一组，用于监测品种间和长期的遗传多样性。这些信息应该有助于加拿大安格斯协会评估其牛相对于其他参与安格斯牛育种的主要国家的多样性和有利等位基因的水平。
