What influences the age of onset of DC, and can this be modulated genetically?

是什么影响 DC 发作的年龄？它可以在遗传上进行调节吗？

A rare exception is the KE family, a large three-generation pedigree in which approximately half of the members are affected with a severe speech and language disorder which appears to be transmitted as an autosomal dominant monogenic trait.

一个罕见的例外是KE家族，一个庞大的三个世代的谱系，其中将近半数的成员受到严重的言说和语言失调的影响，显示受到以此种遗传作为常染色体显性单的基因起源特徵。

Environmental factors play a role in multifactorial inheritance.

环境因素在多基因遗传中有影响。

The findings of previous epidemiologic studies suggest that asthma is a multifactorial disease influenced by both genetic and environmental factors.

以往的流行病学研究发现，哮喘是一种受遗传和环境两方面因素影响的多因素疾病。

BACKGROUND Essential hypertension is a multifactorial disease affected by both environmental and genetic factors.

长期以来人们一直认为，药物的疗效和副作用在个体间的差异可能会受遗传因素的影响。

They are often morphologically distinct from A chromosomes, being smallerand more highly heterochromatic in most cases. B chromosomes do not pair with Achromosomes, and they are inherited in a non-Mendelian way, exhibiting meiotic andmitotic instability and nondisjunction. However, B chromosome DNA is quiteidentical to the corresponding sequence on the A chromosome complement. So far afew B chromosome specific DNA sequence have been identified. Specific DNAsequences on B chromosome have been the attractive research area on Bchromosomes.

现已在千余种植物和近三百种动物中被发现。B染色体与物种中正常染色体不同：独立于整倍体基因组之外，减数分裂时不与A染色体发生联会和配对，细胞分裂后期不分离，非孟德尔遗传，富含异染色质，不含对宿主主要性状有影响的基因等。B染色体DNA的分子组成既与A染色体极为相似，具有A染色体DNA分子组成的一般特征：富含重复序列和转座成分，染色体三大功能组件DNA高度同源；又与之相区别，含有B染色体特异的DNA序列，这些DNA序列可以为探讨B染色体的起源和进化提供有价值的信息。

On basis of shoot regeneration system of "Northland" leaves, several factors that influenced genetictransformation were studied.

在建立'北陆'叶片不定芽再生体系的基础上，对影响根癌农杆菌遗传转化的各因素进行了研究。

So ontogeny is not only the result of the interaction of heredity and environment, it is also influenced greatly by th e initial structure and substantive motility.

所以 ，个体发展不单是遗传和环境相互作用的结果，还要受其原有心理结构和主观能动性的巨大影响。

The book, third edition, introduces the principles of genetics and statistics that are relevant to population studies, examines the forces affecting genetic variation from the molecular to the organismic level, and descripts molecular methods used to study variation in natural populations, as well as explanes the relevant estimation theory using actual data.

该书第三版，介绍与种群研究有关的遗传学与统计学原理，检测从分子到生物体水平遗传变异的影响因素，以及描述用于自然种群变异研究的分子方法，和运用真实数据解释相关的估计理论。

The difference of GMP content among different varieties was controlled mainly by inheritence. Environment factors had certain influence ott it.

品种之间GMP含量的差异主要由遗传决定，环境条件对GMP含量有一定影响。
