For this purpose, genotyping was performed on males of 18 Angus, 23 Jinnan cattle, 20 Limousin, 28 Luxi cattle, 26 Qinchuan cattle, 29 Simmental, 29 Charolais. In the association studies traits of interest were analyzed using the RFLP-PCR and GLM procedure of SAS 9.1 and least square means of the genotypes were compared by the Tukey' s test.

基于这一目标，应用RFLP技术对18头安格斯，23头晋南牛，20头利木赞，28头鲁西牛，26头秦川牛，29头西门塔尔牛和29头夏洛莱牛进行了基因型分型，SAS 9.1的GLM过程中的Duncan's 检验对不同基因型之间进行了多重比较分析，结果表明，EcoRⅤ位点与体重、日增重、眼肌面积和嫩度之间存在显著生物学相关，并且AG基因型个体与其它基因型相比在日增重和嫩度上存在显著差异（p0.05），而AA基因型个体相对于其它基因型具有较大的眼肌面积（p0.05）。

Four families with hemophilia A were analyzed and 2 of them were informative for linkage analysis.

在该群体的男性个体中观察到7种基因型，女性个体中观察到17种基因型，观察杂合度为0.432，多态信息含量为0.7335。

In order to reduce calculation error, the frequency distribution of average values is used to compute the mixed distribution's digital features of each component distribution, thereinto, the number of the component distribution is determined by AIC, choose the number that meets the minimum value of AIC as the component number of mixed distribution, and the other parameters are estimated by EM algorithm; Secondly, because each component distribution is corresponding to a kind of major gene genotype, according to the values of the average and variance of the each component distribution, we can use the limit error of the normal distribution to plot each individual into the correspondent component distribution, namely into correspondent major gene genotype. Then we regard each major gene genotype as a treatment level of one-way analysis of variances, and the one-way multivariate analysis of variance is carried out to calculate the covariance matrix of major gene effect, covariance matrix of polygene effect, covariance matrix of environment effect and so on; At last, combining the weights of the each component distribution of mixed distribution, we can calculate the variance of major gene effect, the variance of polygene effect, environmental variance and the genetic gain of the quantitative trait.

为减小计算误差，本研究采用均值的频数分布来计算各成分分布的数字特征，其中成分分布个数根据AIC准则，选择使AIC值达到最小的成分分布个数作为混合分布的成分分布数，分布中其它参数的确定利用EM算法来估计；其次，每个成分分布对应一种主基因基因型，根据各个成分分布的均值和方差，利用正态分布的极限误差将每个个体划分到相应的成分分布中，即相应的主基因基因型中，将每种主基因型作为单因素方差分析的一个处理水平，对其进行单因素的多元方差分析，分别计算主基因效应协方差阵、多基因效应协方差阵、环境协方差阵等参数；最后结合混合分布中各成分分布的权重即各主基因基因型的分离比例，计算主基因效应方差，多基因效应方差和环境方差，以及遗传力等参数，进而计算该数量性状的遗传进展。

The results of all ABO genotyping in 50 families observe the Mendel's Law and were fully consistent with their ABO phenotypes.

同一个体的ABO基因型与ABO表型结果完全相符。100例认定嫌疑人的强奸案中混合斑精子的ABO基因型与相应嫌疑人血样的ABO基因型结果完全一致。

An association of ACE I/D polymorphism with myocardial infarction was found in a subpopulation younger than 60 years, which was strengthened in patients of myocardial infarction with obesity.

在研究的样本中，未发现ACE基因型与心梗相关；但在年龄60岁及以下的个体中，DD基因型与心梗显著相关，且这种相关在合并肥胖的个体中进一步加强。

The results showed that the clonal reproduction was preponderant, but it has still a high genetic diversity (Ho=0.7148). At the same time, Corylus heterophylla Fisch genetic individual was found. A single cluster was basically a genetic individual; adjacent clusters were basically the same genotype and clonal reproduction has larger percentage.

结果表明：平榛虽然克隆繁殖占有优势，但仍具有较高的遗传多样性(Ho=0.7148)；同时确定了平榛的遗传个体，同1株丛内个体基本上为1个独立的遗传个体，相邻的株丛个体基因型基本一致，克隆繁殖比率较大。

The genotype with foregone normal and individual red blood cell is BB, Bb, the genotype of exsanguine patient is hook cell Bb.

已知红细胞正常个体的基因型为 BB、Bb，镰刀型细胞贫血症患者的基因型为 bb。

On the basis of a simplified assumption that the target loci are introgressed and the genetic background are independent,the probability of selecting individuals with desired genotypes in each generation is approximately estimated combining analytical approach and simulation according to the graphic genotypes of backcrossing parents.The minimal sample size required to obtain at least one desired individual with a given probability is estimated.

在假定所需转移的目标基因座与遗传背景之间为相互独立的简化假设下，可以通过将解析方法与基于回交亲本图示基因型的模拟方法相结合，近似地估计出在每一世代中选到所需基因型的概率，进而估算出在一定概率水平下至少获得一个符合要求的个体所需的最小样本容量。

A it is predominantly derived from the initial variety or from a variety which itself was predominantly derived from the initial variety, while retaining the expression of essential characteristics that result from the genotype or combination of genotypes of the initial variety; an essentially derived variety may have been obtained by the selection of a natural or induced mutant or of a somaclonal variant, by the selection of a variant individual from plants of the initial variety, by backcrossing, by a transformation by genetic engineering, or by any other similar method

一个品种主要由原始品种演化而来，或主要由原始品种的实质性派生品种演化而来，同时保留了来自原始品种基因型或基因型组合的基本特征的表达；一个实质性派生品种可能通过选择自然变异或诱变或体细胞无性变异、原始品种植株的个体变异的选择、回交、基因工程的改造或任何其它类似方法而获得。
