隐性性状

Using canonical correlation analysis method to analyze the relation of nine stature traits and three semen quality traits of the line H males of recessive white rock, it indicate that the first canonical correlation coefficient between two traits is 0.8481(p.05), which takes up about 50.5%in total correlation information. The correlation relation between stature traits and semen quality mainly engendered by the heart girth(X8) and sperm concentration(X11), and it is a negative correlation .

用典型相关分析法对隐性白H系公鸡9个体尺指标与3个精液品质指标进行了相关分析，结果表明：两组性状间的第一典型相关系数为0.8481(p.05)，占总相关信息的50.5%，体尺性状与精液品质之间的相关关系，主要是由胸围(X8)和精子密度(X11)之间的密切相关所引起，此相关为负相关。

Although august weismann had expressed doubts about the theory earlier, it did not fall out of scientific favor until the 1890s, when a series of experiments by james cossar ewart in scotland and other researchers in germany and brazil failed to find any evidence of the phenomenon. the result obtained by morton could probably be caused by the display in the offspring of the recessive genes inherited by the morton's mare from her parents/grandparents.

虽然august weismann早先对这个理论表示怀疑，但直到19世纪90年代，这理论仍然获得科学上的支持，直到 james cossar ewart in scotland 及其他一系列研究者在德国和巴西所做的一系列实验都未发现有关现象的证据。morton所观察到的现象可以被解释为后代从它的父母/祖父母身上继承了隐性基因，并表现出性状。

ugust Weismann对理论表示怀疑(也就是你回应提到马交配的实验，在本段的上半部有提及我就不引用了)但这理论始终得到学界支持，直到James Cossar Ewart在苏格兰，德国，巴西所做的系列实验都无法发现有关现象的根据；Morton观察到的，可以说是马遗传了亲代或祖父母的隐性基因，并表现出性状也就是最初实验马交配发表先父遗传的人

The results showed the resistance was controlled by at least two pairs of genes, and was incompletely recessive. Effect of backcross was very significant and that of reciprocal cross was not. Resistance was dominated by nuclear genes, narrow inheritability was comparatively high. The resistance was in keeping with additive-dominance model, and dominance was dominating, and showed a quantitative character.

结果表明：苦瓜对白粉病的抗性受两对以上基因控制，两对主基因抗病相对感病为不完全隐性，回交效应极显著，正反交效应差异不显著，抗病性主要受核基因控制，两对主基因的狭义遗传力较高，符合加性－显性模型，加性效应较大，抗性效应在亲本和F1间存在极显著正相关，表现为数量性状遗传的特点。

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。

The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

结果表明，白来航鸡的白羽和寿光鸡的黑羽对藏鸡麻羽的遗传方式是完全显性遗传；麻羽是由两个或两个以上的等位基因决定的，只有同时存在这两个或两个以上的等位基因，才可能表现出麻羽来；决定胫色性状的Id/id基因为伴性遗传，隐性基因id在纯合子时有个逐步表达的过程；本研究证实了所用白来航公鸡胫色性状的基因型为显性纯合子。

Feather color and shank color performance and separated proportion of F1 and F2 were observed. The results indicate that white feather of White Leghorn chicken and black feather of Shou-Guang chicken are complete dominance heredity to hemp feather of Tibetan chicken. Hemp feather is determinate by two or more than two alleles. Only these two or above two alleles is of concurrence, then hemp feather displays possibly. Id/id allele decided shank color is of sex-linkage inheritance, recessive gene id homozygote has process which expresses gradually. We confirm that genotype of shank color in White Leghorn chicken in this paper is the dominant homozygote.

Thus, if height is controlled by two genes, A and B, and tall and short forms are determined by dominant and recessive alleles respectively, then the cross Aabb × aaBB would give an F1 AaBb, containing both dominant genes for tallness.

假设，高度性状是由两个基因 A 和 B 共同控制，且高与矮两种表型分别为等位基因中的显性和隐性基因所决定，那么， Aabb × aaBB 杂交的结果是 F1代为 AaBb ，含有决定高性状的两个显性基因。

Preliminary genetic analysis demonstrated that the mutant character was recessive contrast to two-row of Pudamai 2, controlled by one pair of recessive genes, and was one variant of row- types.

初步遗传分析表明，该突变性状相对于受体亲本莆大麦2号的二棱为隐性，是穗棱型变异的一种，受一隐性基因prb控制。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
