同基因的

A haploid cell that results from the meiotic division of an oocyte and becomes a female gamete or an ovum .

同卵双生的从同一受精卵中产生的，具有相同基因结构和相似外貌的孪生子的；单卵的

The survival of oospores which were produced in the media was assessed after a winter. The methods promoting the oospore germination and the factors affecting the oospore germination were also investigated. Identfication of mating type, resistance to metalaxyl and isozyme genotype were performed on the F1 generations and parental isolates of oospores.

对马铃薯晚疫病菌在培养基上产生的卵孢子越冬后的存活能力、诱导卵孢子萌发的方法、影响卵孢子萌发的因素和卵孢子亲本及F_1代菌株的交配型、对甲霜灵抗性和同工酶基因型进行了初步测定和研究。

The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。

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%。

Even now, Ashkenazim tend to marry among themselves. In the past they did so almost exclusively.

前者被说成是社会原因引起的，如浓烈的价值观教育的传统；后者则被说成是基因隔离的结果，不过即使是现在，德系犹太人还是愿意同本族人结婚，在过去，就更是如此了。

In model plant Arabidopsis thaliana, also from Brassicaceae, the TRANSPARENT TESTA 12 (TT12, AtTT12) gene is seed coat-specific and encodes a vacuolar flavonoid/H+ antiporter, transporting cytoplasm-synthesized glycosylated flavan-3-ols to the vacuoles for further polymerization into seed coat pigments.

同属十字花科的模式植物拟南芥中，种皮特异表达的TT12（透明种皮12，AtTT12）基因编码一种液泡型类黄酮/H+-逆向转运蛋白，将胞浆内合成的糖苷化的黄烷-3-醇转运到液泡中，供进一步聚合形成种皮色素。

Than cross-pollinated plants, which harbor more genetic variability.

参考译文：由于持续的同种繁殖，同株授粉的植物比异株授粉的植物表现得更具一致性，从而使基因突变可能性更大。

They are formed by different alleles, and are a valuable tool for detecting genetic variation.

同功酶是由不同的等位基因所形成，是研究遗传变异方面的一种有力的工具。

Reinhardtii is both necessary and sufficient to cause the cells to differentiate as MT- isogametes.

reinhardtii藻的特殊基因MID的存在，生殖细胞才得以具备充分能力辨别真正的MT同形配子。

Because this population of birds is so small, conservationists worry about inbreeding, and are considering moving in some chickens from Kansas, where they are more numerous, to boost numbers diversify the gene pool.

由于这里的北美草原松鸡数量很少，自然资源保护者们担心这会导致同系交配，所以正考虑从数量较多的 Kansas 转移一些过来，这样就能使松鸡的基因多样化了。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
