In this study, analyses of yield combining ability, SSR molecular markers was made to study in 198 combinations which come from different strains in the basic S1 66 plants of 39007 and 39002 groups and three types of tests in Incomplete Diallel Cross Experiments.

This paper reports the restriction allele frequencies, polymorphism information contents and heterozygote frequencies of the restriction sites of D4S10 locus, pK082/Hind Ⅲ(2),pK083/EcoRI(1) and pK081/EcoRI(2), detected by three sub-clones of the G8 probe and tries to do presymptomatic diagnosis of Huntington 's disease for phenotypically normal family members in two HD families.

报道53例样本D4S10基因座由G8探针3个亚探针检出的限制酶切位点pK082／HindⅢ（2）、pK083／EcoRⅠ（1）和pK081／EcoRⅠ（2）的等位片段频率、多态性信息含量和杂合子频率，并试对2个Huntington舞蹈病家系成员作症状前诊断。

Personality traits were evaluated by Eysency Personality Questionnaire that was compiled by Eysency and revised by Gong. Standard scores of Psychoticism, Extraversion and Neuroticism were calculated, and taking 50 points as a boundary. Each dimension was assigned into 2 grades non-psychotic type (P0) psychotic type (P≥50), introversion type (E0), extraversion type (E0), non-nervous type (N0) and nervous type (N≥50). 5 mL ulnar vein blood was obtained without adding decoagulant, and then serum was removed. Genome DNA was extracted from blood clot by conventional chloroform for PCR analysis. PCR product was sequenced by pyrophosphoric acid. SNP was determined by PSQ96 MA sequenator. Allele frequency was analyzed by mass spectrometry.

人格评定采用Eysency编制，龚耀先修订的艾森克人格问卷、计算精神质，内外问，神经质3个个性维度的标准分，并以50分为界，将各维度分为两个等级：非精神病倾向型（精神质0）、精神病倾向型（精神质≥50）；内倾型（内外向0），外倾型（内外向≥多50）；非常经质倾向型（神经质0），神经质倾向型（神经质≥50）取肘静脉血5 mL，不加抗凝剂，弃血清，血凝块常规酚氯仿提取基因组DNA，进行PCR分析PCR产物应用焦磷酸测序PSQ96 MA测序仪进行SNP检测，用质谱法进行及等位方基因频率分析。

Seven hundred rice landraces which were distributed in six geographic groups in China were analysed using nine isozyme loci.

本研究对中国栽培稻6个地理分布群的700份古老地方栽培品种进行9个多态性等位酶基因位点的遗传多样性分析。

In Tibetan yaks, there were not polymorphisms, and only B allele was found.

在西藏牦牛中，只检测到一个等位基因B，未发现多态性。

We show that over timescales ranging from 500～10000 years, allele frequency data for polymorphic allozymes reveal a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and that populations in the invaded range are more subdivided genetically than those in the native range of each species.

从500～10 000年的时间尺度上，多态的等位酶位点上等位基因频率的数据表明：1）遗传多样性沿入侵路线呈不断下降的趋势，支持了冰河期避难所作为遗传多样性中心的作用；2）入侵地区的种群与该物种原产地的种群相比，遗传上的分化更为强烈。

The data of polymorphism information contents, effective number of alleles and heterozygosity indicated that, the genetic variation of Small-tailed Han sheep was the highest, Mongoha sheep was the second, Lanzhou large tailed sheep was the third, Tibet sheep was the fourth, Poll Dorset sheep was the lowest.

多态信息含量、有效等位基因数及群体杂合度数据表明，小尾寒羊遗传变异最大，其次是蒙古羊、兰州大尾羊、藏羊，无角道赛特变异最小。

Haplotype is a lineable combination of alleles at multiple loci that are transmitted together on chromosome or mitochondrion.

单倍型是指一条染色体或者线粒体上紧密连锁的多个等位基因的线性排列，作为一个整体遗传给子代。
