遗传学

By the end of World War II eugenics had been largely abandoned, though current trends in genetics have raised questions amongst critical academics concerning parallels between pre-war attitudes about eugenics and current "utilitarian" and social darwinistic theories.

在第二次世界大战结束时，优生学已经基本上被抛弃了；但是在遗传学的当代动向中，爱评论的学者关注战前的优生学观点与当代的&功利主义&和社会达尔文理论的相似之处，提出了各种疑问。

起源于籼稻体细胞培养的联会消失变异的细胞遗传学研究。

The study of optimal designs for diallel cross experiments has been receiving considerable attention recently.

摘要 Diallel cross实验应用於生物科技的遗传学上，在近几十年来有钗h研究遗传，育种，配对等的相关文献陆续被提出，而有关最适的diallel cross实验设计则在最近被注意到。

Diallel analysis has been broadly used as an important tool of genetic analysis in classical quantitative genetics, which advanced the development of genetics studies and breeding practices.

双列杂交分析是经典数量遗传学中应用最为广泛的一种重要的遗传分析方法，推动了遗传研究与育种实践的发展。

To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制，本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208％，同时，建立了一种保持精子基本形态的胰酶去凝聚的方法，为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究，提供了新的手段。

And molecular genetic analysis was performed on DNA extracted from the twins Ⅳ-3 and Ⅳ-4 to identify whether they are monozygotic twins or dizygotic twins Results The family history was consistent with a maternal inheritance and the proband exhibited a typical clinical feature of LHON.

最后应用分子遗传学技术对该家系中的一对双生子（其中一人为先证者，另一个未患病）进行DNA多态性的比较分析以鉴定其卵性。

Herbacium were isobilateral leaves, and those of G. hirsutum and C. barbadense were dorsiventral leaves. The reciprocal F〓 of cross G. arboreum×G. herbacium were also isobilateral leaves, while reciprocal F〓 cross of G. hirsutum×G. barbadense were also dorsiventral leaves. The quadrispecific hybrids F〓 were isobilateral leaves, regardless of their cytoplasms. The structures of the leaf stalks and the stems were analogous to each other among the four cultivated cotton species except their diameters varied with species.

四个栽培棉种及其种间杂种F〓的形态学和细胞遗传学观察四个栽培棉种的植株、叶片、茎杆以及花器等器官都有明显的差异；叶片、茎杆以及叶柄的横切面结构观察结果表明，两个二倍体栽培棉种的叶片横切面构造为等面叶，两个四倍体栽培棉种却均为背腹叶；F〓正反交的叶片也为等面叶，F〓正反交F〓仍为背腹叶，而它们的四元杂交种均为等面叶；四个栽培棉种的叶柄和茎的横切面结构基本一致，只是直径形状和和维管束多少的不同，四元杂种的叶柄和茎的横切面结构的差异不明显。

Over 3000 years ago, however, the ancient bronze designers of Sanxingdui constructed human eyes in a "mosaic" both dorsoventral and nasotemporal divisions.

西方学者在19世纪提出了眼睛的&拼合&模型，当今发育生物学、遗传学以及分子细胞生物学研究结果进一步证明了该模型的合理性。

Among 13 DRB1 alleles detected in Drung ethnic, a unique feature of its allele distribution is having predominant homozygotes (64.9%) in all studied populations. In Drung HLA-DRB1〓14011 is highly prevalently presented with the allelic frequency of 70.07%.

独龙族中检出13种等位基因，其遗传学显著特点是纯合子类型检出较多，纯合子36个，占被检样品的64.9％，DRB1*14011分布占绝对优势，占被检出等位基因的70.07％。

In this experiment, 7 microsatellite DNA loci linked with PPAR gene were selected from the published genetic map of chromosome 13 in pig, and polymorphisms of these microsatellites in 100 samples from Sutai pigs (Duroc × Erhualian) populations were detected.

从已公布的猪 13 号染色体连锁图谱中选择与PPAR 基因连锁的 7 个微卫星座位，在苏太猪群体中对这些位点进行群体遗传学特性分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
