等位基因的

Gene frequency The proportion of an allele in a population in relation to other alleles of the same gene.

基因频率：指某一特殊类型的等位基因在群体中所有等位基因总数中所占的比率。

A person with a pair of identical alleles for a particular gene is a homozygote; a person with a pair of dissimilar alleles is a heterozygote.

一个人如果带有某个基因的两个相同的等位基因，是纯合子；如带有两个不相同的等位基因，则为杂合子。

A person with a pair of identical alleles for a particular gene is a homozygote; a person with a pair of di imilar alleles is a heterozygote.

一个人如果带有某个基因的两个相同的等位基因，是纯合子；如带有两个不相同的等位基因，则为杂合子。

Meanwhile, Tibetan sheep (breeded in Sanjiaocheng of Qinghai, Huangcheng and Gannan of Gansu ), Mincounty Blank Fur sheep and Texel and Poll Dorset were controlled. The results indicated that polymorphism was tested at the loci of Hb, Tf and Es, that erythrocyte protein 1 and 2 were monomorphism. There were a couple of allele and three genotypes at the loci of Hb and Es. There were 10 genotypes at the locus of Tf, which was determined by 5 alleles.

结果表明，青海细毛羊和甘肃高山细毛羊的血红蛋白、转铁蛋白和酯酶基因座上存在丰富的多态性，其中Hb和Es位点受一对等位基因控制，共构成3种基因型；Tf位点受5个等位基因控制，共构成10种基因型；而红细胞蛋白质-1（EP-1）和红细胞蛋白质-2（EP-2）基因座均呈显单态；青海细毛羊的AMY基因座具有AMY1、AMY2、AMY3三种同工酶，其中AMY2呈多态，有AMY2A和AMY2O两种表现型，而甘肃高山细毛羊的AMY呈显单态。

The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

结果表明，白来航鸡的白羽和寿光鸡的黑羽对藏鸡麻羽的遗传方式是完全显性遗传；麻羽是由两个或两个以上的等位基因决定的，只有同时存在这两个或两个以上的等位基因，才可能表现出麻羽来；决定胫色性状的Id/id基因为伴性遗传，隐性基因id在纯合子时有个逐步表达的过程；本研究证实了所用白来航公鸡胫色性状的基因型为显性纯合子。

Feather color and shank color performance and separated proportion of F1 and F2 were observed. The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

To date, one allele coding fast acetyltor (wild-type NAT2*4) and several mutated alleles coding for impaired acetylator activity have been identified.

NAT2基因具有高度的多态性，至今为止1个快型野生型等位基因(NAT2*4)和一些慢型野生型等位基因已被证实。

The average percentage of polymorphic bands are 72.06% for ISSR and 66.67% for RAPD respectively. The genetic diversity of ginkgo revealed by ISSR (the average effective number of alleles is 1.8780, the average Nei"s gene diversity is 0.4652, and the average Shannon"s information index is 0.6574) are all higher than those by RAPD (the average effective number of alleles is 1.7842, the average Nei"s gene diversity is 0.4317, and the average Shannon"s information index is 0.6211), while the standard errors of the parameters estimated by ISSR were lower. Therefore, ISSR molecular markers are more suited than RAPD molecular markers when testing the genetic diversity of ginkgo populations and determining the genetic relationship of among populations or among individuals which are much similar hereditarily.

本文应用RAPD和ISSR两种分子标记技术，选取中国5个可能的野生银杏居群共计75个样品，对其遗传多样性进行了研究，得出以下结论：(1)用筛选出的12个RAPD引物和10个ISSR引物进行PCR扩增，分别扩增出65条和68条重复性高、清晰的条带，多态性位点百分率分别66.67%和72.06%，ISSR揭示的银杏遗传多样性(平均有效等位基因数目为1.8780，平均基因多样度为0.4652，平均信息指数为0.6574)高于RAPD所得到的结果(平均有效等位基因数目为1.7842，平均基因多样度为0.4317，平均信息指数为0.6211)，其所估算参数的标准差要低于RAPD所估算出的值，因此，在研究亲缘关系非常近的银杏物种的遗传多样性并试图确定居群间或个体间的遗传关系时，ISSR分子标记技术比RAPD分子标记技术更为合适。

The analytic results showed frequencies of allele B or A and allele C were significantly different (P.01), while Taihe Silkies chickens and Baier chickens were different (P.05), it could conclude that the SNP may have relationship with thiamine content.

等位基因A和B的频率极显著高于等位基因C的频率，且泰和乌骨鸡与白耳鸡差异显著，故推测所检测到的基因座与肌肉硫胺素含量相关。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
