How to find information about human genes and hereditary disorders with OMIM;
如何利用OMIM获取人类基因与遗传失调信息
Analysis of genetic covariances was made between plant height at different growing stages and eating and cooking qualitative traits of rice.
进一步分解各项遗传协方差分量发现,不同性质遗传相关分量差异也较大,表观直链淀粉含量(AAC) ,胶稠度(GC) ,粘度速测仪(RVA) 谱与株高的相关性主要以加性相关( CA/Am 和CA/Am) 和细胞质相关( CC/C) 为主。
In the article, the linkage strengty of genes is expressed using linkage value, the mathematic expression of genetic covariance of two characters in F 2 and backoross generations with K pairs of linkage genes effecting two characters separatively is extended, and the resolution form of its component is obtained.
本文用连锁值表示基因的连锁强度,推广了K对连锁基因分别作用于两性状时F2代及回交世代两性状的遗传协方差的数学表达式,得出了其分量的分解形式。
Genetic covariances bewteen these two sets of traits were studied with a mixedlinear model method.
用2个籼型水稻光温敏核不育系和7个粳型广亲和品种为材料,按NCⅡ设计配制杂交组合,获得亲本、F1及F2代的籽粒群体,对8个主要品质性状和6个农艺性状进行测定,按混合线性模型的分析方法对品质性状与农艺性状之间的遗传协方差进行了研究,结果表明:在籼粳亚种间杂交组合中,稻米理化品质性状与植株农艺性状之间的遗传协方差大都为直接加性/母体加性协方差,外观品质性状与农艺性状之间的遗传协方差则主要是直接加性/母体加性协方差和母体加性/母体加性协方差,细胞质效应协方差也普遍存在。
