Relationships between longevity and conformation traits in Czech Fleckvieh cows
cattle Czech Fleckvieh longevity
2015/6/8
The relationships between conformation and longevity traits were analysed in 58 493 Czech Fleckvieh cows first calved from 1994 to 2003. All cows were scored for conformation during the first lactatio...
用4个微卫星标记分析7个绵羊群体之间的遗传关系Genetic Relationships Among Seven Sheep Populations Using Four Microsatellite Markers
绵羊 微卫星 遗传多态性 分子系统发生
2008/1/8
摘要
分析了4个微卫星基因座BM143、OarHH35、OarAE101、BMS2508在7个绵羊群体(小尾寒羊、湖羊、乌珠穆沁羊、萨福克羊、多赛特羊、夏洛来羊、多赛特公羊×小尾寒羊母羊F1代杂种羊)286只绵羊中的遗传多态性。结果表明,这4个微卫星标记在7个绵羊群体中的等位基因数分别为9、11、14和9,其多态信息含量/有效等位基因数/杂合度分别为0.7073/3.7231/0.7314、0....
杉科、柏科的系统发生分析——来自28S rDNA序列分析的证据Phylogenetic Relationships among the Genera of Taxodiaceae and Cupressaceae from 28S rDNA Sequences
28S rDNA 杉科 柏科 系统发生 替代速率
2007/12/30
摘要对杉科(Taxodiaceae)与柏科(Cupressaceae s.s.)的28S rRNA基因的部分序列(约630 bp)进行PCR扩增、序列测定和系统发生关系分析,用简约法和邻接法构建的系统发生树基本一致。结果表明,杉科与柏科构成一个单系群,支持将杉科、柏科(Sciadopitys除外)合并为一个科——广义柏科(Cupressaceae sensu lato)的观点。在广义柏科中,Tai...
