Sex is hereditary. If your parents never had it, chances are you won't either.

性是可遗传的,如果你父母没有,你也没有机会。

Epigenetics is the study of heritable changes in gene expression that occur without a change in DNA sequence.

表观遗传学是研究基因表达中可遗传的改变,而在DNA序列上没有变化。

The information is heritable and coded in such a way as to allow variation and thus evolution.

这些信息通过这种方式变成可遗传的,可编码的,因此产生物种的不同,进而发生进化。

What natural selection does is change the relative frequencies of alternative phenotypes, insofar as they are heritable.

自然选择的作用是在可遗传的表型范围内,改变可供选择的替代表型的相对频率。

The inheritance and maintenance of the DNA sequence has been explained by a semiconservative mechanism of replication in which a complementary new strand of DNA is synthesized along each parental strand, resulting in an inherited double-stranded molecule that contains old and new DNA.

DNA序列的遗传和维持可以被复制的半保留机制所解释,在这一机制中互补新链DNA沿着每条父本链合成,产生了可遗传的含有新旧DNA的双链分子。

Thus the early biparental inheritance might be caused by occational male plastid transmission.

本研究在菜豆不同品种成熟花粉的生殖细胞中都没检测到细胞器DNA,表明父系可遗传的细胞器的排除在不同品种间是一致的,即不存在基因型的影响,我们认为菜豆的早期遗传分析得出的双亲遗传的结论可能是由于雄性质体的偶尔传递。

Conclusions— Hemodynamic and chronotropic responses to exercise are heritable and demonstrate suggestie linkage to select loci.

结论——对运动的血流动力学和变时性反应是可遗传的,并提示有与选择的基因座有可能的遗传连锁。

These findings show that frontotemporal lobar degeneration is a highly heritable disorder but heritability varies between the different syndromes.

这些发现表明额颞叶变性是高度可遗传的疾病,但是不同症状的遗传能力差异很大。

Combining electron microscopy observation with DNA fluoresence detecting technique, it is systematically studied the ultrastructure of microspore, the distribution of plastid and mitochondria and the changes of organelle DNA at different developing stages in Phaseolus vulgaris, Pisum sativum, and Lilium Spec.(L. davidii and L. regale).

基于上述的情况,本研究应用电镜和DNA荧光技术系统研究了菜豆、豌豆及百合属中王百合和兰州百合这些植物种小孢子发育的超微结构,质体和线粒体的分布形式及其DNA的变化情况与遗传的关系,并应用RFLP分析了兰州百合的质体遗传方式,同时对另一种可遗传的细胞器——线粒体的遗传方式也进行了研究。

In evolutionary studies, because heritable non-genetic variations are often induced by the environment, we have to expand our notion of heredity and variation to include the inheritance of acquired variations, the once disparaged idea that was part of Lamarck's theory.

在进化研究中,因为可遗传的非基因变异通常是由环境引起的,所以我们应该将我们的遗传和变异概念扩大到包括获得性变异的遗传--这一被轻视的观点是让-巴提斯。拉马克(Jean-Baptiste Lamarck)理论的一部分。
