可遗传的

Literature Research The etiological factors of POF are not still clear. The changes of sites and numbers in X chromatosome, X; autosome translocations, a forkhead transcription factor gene (FOXL2) mutations, FRAXA premutations and inhibits gene mutations are found in POF patients, so genetic disorders have been thought to be involved. Irradiation, chemotherapy or pelvic operations can damage ovaries and cause ovarian atrophy and failure, so it is thought one factor of POF.

一、文献研究 POF的确切病因目前尚不清楚，从POF患者体内检测到X染色体上位点和数目的变化，X染色体与常染色体间的平衡易位，脆性X基因前突变，FOXL2基因突变，抑制素基因突变等，故认为POF发生与遗传因素有关；由于放射、化疗或盆腔手术等可损伤卵巢，导致卵巢萎缩，出现卵巢衰竭，故也是导致POF的因素之一。

We give a group of circular filter functions, use genetic algorithm to select the frequency band of larger divisibility value, and design the expression of chromosome and the solution of fitness.

给出了一组圆形滤波函数，并使用遗传算法来选择可分性较大的频段，设计了染色体的表示方式和适应度的求法。

We give a group of circular filter functions, use genetic algorithm to select the frequency bands of larger divisibility value and to estimate the parameters of circular filter functions, and design the expression of chromosome and the function of fitness.

给出了一组圆形滤波函数，并使用遗传算法来选择可分性较大的频段和进行圆形滤波函数的参数估计，设计了染色体的表示方式和适应度函数。

It is suggested that it is better to indicate the variability within breeds by average heterozygosity based on microsatellite polymorphisms, which showed high polymorphisms and codominant inheritance of the markers, where as differences between populations and even specific characteristics with in a population are reffected clearly and directly by RAPD.

由于微卫星标记多态性程度高且等显性遗传，因而通过它计算杂合度可以较好地反映群体内的变异；RAPD则在反映群体间的区别甚至某一群体的特征时可提供明确而直接的信息。

It results from an inappropriate immune response, in genetically susceptible individuals, to microbial antigens of commensal microorganisms.

他起因不适当的免疫应答、遗传易感个体及共生的微生物抗原，并可被特定的环境因素所诱发。

A same marker locus could associate with multiple traits with its alleles performed in their own way in direction and size, and the covariation of a same allele performed in two related traits might be the genetic basis of their phenotypic correlation.

同一标记位点可与多性状关联，其等位变异在不同性状间各有其表型效应的方向和大小；等位变异在相关性状效应上方向、大小的异同解释了性状间正、负相关的遗传原因。

Third, Construction of the physical map covering the target gene using large fragment libraries.

只要目的基因的表型可以鉴定，并能通过遗传连锁分析将它的位置定位在染色体上距离很近的两个分子标记之间，它可用于任何基因的克隆。
