对偶基因

Moreover, the apo-E epsilon 4 allele is a major risk factor for neurodegenerative conditions, including Alzheimer's disease.

更重要的，apo-E epsilon 4 对偶基因是神经退化疾病，包括老年痴呆症的主要危险因素。

The marker loci of chromosomes 6 and 2 respectively had the highest (98％) and the lowest (90％) homozygosity ratio in the RIL population.

除此之外，本研究在RIL族群中发现16个新分离之对偶基因，为两亲本均不具有之对偶基因。

Edward was found to be heterozygous for sickle-cell trait.

他有一对基因是Ss，那麼S和s这个对偶基因会被写

Alpha-1 antitrypsin is the most abundant circulating protease inhibitor in the body, Dr. Lomas said. Its most common deficiency mutation is the Z allele, where the amino acid lysine is exchanged for glutamic acid at position 342 in the polypeptide chain (Glu342Lys). About 1 in 1700 whites of northern European descent are homozygotes for this mutation and thus have plasma antitrypsin levels that are 10% to 15% below normal, he said.

Lomas博士表示，甲一型抗胰蛋白酵素是身体内最充分的循环蛋白酶抑制剂，最常见的缺损突变在Z对偶基因，该处的胺基酸 lysine与麸氨酸在多胜肽链的第342位置交换(Glu342Lys)；北欧血统白人每1，700人有1人是此一突变的同合子，因此血浆抗胰蛋白酵素值比正常低10%到15%。

The ISSR markers were fitted to a 3:1 ratio of simplex and duplex segregation for the parental alleles, as the sweet potato was expected to be autohexaploid. Fourteen and nine quantitative trait loci linked to specific ISSR markers were detected for traits in (NH×TN27) and (TN27×NH), respectively. Twenty-two of these QTL-mapped markers were unique to the specific traits, and two were linked to two traits in each linkage map. These markers appear to be applicable to crop improvement.

ISSR标识因子符合六倍体亲本对偶基因simplex与duplex的3：1分离比。14与9个与专一性ISSR标识因子连锁之数量性状基因座，分别检测NH×TN27与TN27×NH之性状，其中22个数量性状基因座图绘之标志因子，对於特殊性状而言具有特殊性；每个连锁图谱中，有两个QTL图绘之标志因子与两个性状连锁，这些标志因子应可应用於作物改良。

Objective: To investigate the relationship between the presence of tophi and the TNF-alpha promoter-308G/A polymorphism in gouty patients.

目的：研究痛风石的产生和甲型肿瘤坏死因子促进因子基因－308位置之G→A对偶基因多型性之相关性。

The frequency of the TNFα-308A allele was significantly higher in patients with tophi than in patients without p=0.02, odds ratio

甲型肿瘤坏死因子促进因子基因－308位置之A对偶基因在有痛风石这组病人的比例明显多於没有痛风石的病人p=0.02， odds ratio 5.4， 95% C.I。

These different versions of each marker, called alleles, correspond to different versions of nearby genes.

每个标记的这些不同形式称作对偶基因，与附近不同形式的基因相对应。

A red strain with an inferior dorsal bred to a red strain with a superior dorsal has a much better chance after the spin of the gene roulette wheel than a cross to another color strain.

但是同种的鱼线必须要多，如此才可补齐原有品系鱼种的原有基因（因为由於LINE BREEDING OR INBREEDING 后通常都会遗失掉一些对偶基因因而导致所谓基因弱化的发生）。

"Because of the powerful genetic effects on incubation periods in laboratory animals, vCJD patients identified could represent a distinct genetic subpopulation with unusually short incubation periods for BSE prions, with vCJD so far occurring predominantly in those individuals with short incubation time alleles at these multiple genetic loci, in addition to having the homozygous PRNP genotype of codon 129 methionine," they write.

因为动物实验表现出基因对潜伏期的强力影响，鉴定vCJD病患表现出清楚的基因次族群和BSE传染性蛋白质的不寻常短潜伏期；vCJD病患目前显著地发生在短潜伏期对偶基因者，密码子129蛋氨酸的PRNP 基因是同型合子。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
