杂交后代的性状出现了广泛的分离，花色、株高、花径、重瓣性等性状都有超亲遗传的现象，有利于菊花育种的选择。

Statistical methods designed specifically for mapping QTL controlling endosperm trait have been proposed by several researchers in recent years, but these methods all ignored the influence of the maternal genom.

谷类作物种子的整个发育过程是在母体植株上完成的，母株为种子提供库容和营养，因此种子胚乳性状和胚性状的遗传表达除了受胚乳和胚自身基因型控制以外，还可能受到母株基因型影响。

For our purpose the argument remains good whether we admit or deny the inheritability of acquired characteristics, our point being that in either case the process is necessarily a slow one, though it is plainly more rapid if the hypothesis be true.

无论我们是否承认因用进废退而后天获得的性状的可遗传性，上述论断都是正确的，且该过程是缓慢的，但是如果后天获得的性状可以遗传 [4]，那么这个过程将会更快一些。

The phenotypic characteristics in pines vary widely and the differences of inheritability(h2) are obvious among characteristics and among species.

松树表型性状变异广泛，其不同树种不同性状的遗传力均存在差异。

According to Mather and Jinks model, using generations mean analysis m eth od, the various kinds of gene effects and its percentage of gene-effect-square s um were estimated,and comparative analysis on the gene effects and the importan ce t o inheritance of characters was carried out between the supernumerary spikelet l ines.

黄毅以主穗小穗数在25～30个的二个普通小麦多小穗品系85DH5015、SW94-30921 与三个普通小麦品种组配成6个组合的P1、P2、F1、F2、B1、B2为材料，用世代均值法分析了6个性状的遗传模型并估算了各类基因效应值，比较分析了两个不同来源多小穗小麦品系六个性状各类基因效应的异同及其相对重要性。

The results showed that the general combining abilityand specific comb ining abilityvariations were significant,and the inheritance of grain filling traits were controlled by additive and nonadditive effects.

结果表明，籽粒灌浆性状的GCA和SCA均方达显著水平，说明籽粒灌浆性状的遗传受基因加性效应和非加性效应共同作用。

Significant negative partial phenotypic correlation was observed between the two traits. However, exploring the genetic basis of trait correlation is still necessary in further study.

两个性状表型之间存在显著的负向部分相关，然而，性状相关的遗传基础仍需做进一步的探讨。

The phenotype values of the major gene and polygene mixed inheritance of quantitative trait demonstrate multimodality, showing the mixture of more than one normal distributions, that is corresponding to more than one major gene genotypes, so the selection is different from common quantitative trait in model hypothesis and analysis.

主基因-多基因混合遗传的数量性状，其表型值呈现多峰性，表现为多个正态分布的混合，即对应多个主基因基因型，其选择与普通数量性状的选择在模型假定以及分析上都有很大的不同。

Although several genetic models has been proposed including autosomal-dominant/autosomal recessive, sex-linked, sex-limited, mitochondrial, and multi-gene, none of these models can well-explain the transmission of the disease.

尽管此前已提出包括常染色体显性/常染色体隐性，伴性性状，限性性状，线粒体性及多基因性遗传模式，但均难以很好地解释该病的遗传性。

However, the weedy rice has became an another special type for long time evolution and domestication, so its resistance is superexcellence than the cultivable rice, and also become a natural gene storeroom.

然而，经历漫长的自然进化和某种特定稻作环境的驯化，杂草稻已成为稻种资源的一个特殊类型，较野生稻而言，其特殊生物学性状和抗逆性等优良性状易于在育种中直接利用，是水稻品种改良的重要育种资源，同时也是稻种遗传进化研究的必备材料。杂草稻长期自然生长繁衍，其抗病、虫、寒、旱、盐碱等特性优于栽培稻，而且与栽培稻的亲缘关系相对接近，是一种改良栽培稻抗逆性的天然基因库。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
