Objective The incidence rate of esophageal carcinoma in ChangZhi area located in the TaiHang Mountain, is very higher. The character of general demology and environmental factors were observed and analyzed to explore the susceptibility to esophageal carcinoma in cases and controls with different cytochromeP4501AlExon7 MSP1 genotypes. This could contribute to finding the cause of disease and suggesting the level of predicting the esophageal carcinoma susceptibility.

Ecological analysis of morphological and genetic variation revealed that:(1) The averages of morphological characters were significantly negatively correlated with WSF (2) Dominant frequencies of some RAPD loci were significantly correlated with WSF (3) The correlation between morphological variation and genetic variation was not significant (4) The cluster analysis based on morphological and genetic evidence supported that all population can be divided into three ecotypes: saltmarsh reed, freshwater reed and giant reed.

It is obvious that a characteristic has been inherited in diseases such as haemophilia and traits such as naturally red hair: such things cannot be moulded by experience.

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。

Results: Osteopetrosis is a group of rare, heritable disorders of the skeleton characterized by increased bone density with typical X-ray manifestation. It can be divided into autosomal recessive osteopetrosis and autosomal dominant osteopetrosis. The prognosis vary greatly in different clinical type.

结果：石骨症是罕见的家族性先天性骨疾病，以骨密度增高为主要表现，分常染色体显性遗传和常染色体隐性遗传，分型不同，临床表现不同，X线有特征性改变，治疗上以对症治疗为主，造血干细胞移植被用于治疗本病。

Telegony is a theory in heredity that offspring can inherit the characteristics of a previous mate of one or both parents.

先父遗传是一种遗传上的理论，这个理论是说，后代能继承父母双方中一方的前任伴侣的特征。

Efficient detector generation algorithm is the kernel of anomaly detection. Aiming at low true positive value, unhandy matching threshold value and large detector set size of existent algorithms, a novel detector generation algorithm based on multiple populations genetic algorithm is put forward in this paper. According to morphologic analysis of intrusion detection system and covering problem principle, self set is divided into several partitions on the basis of their characters.
