Pingbianensis flowers were ants (Aphaenogaster smythiesii Forel,Formicidea), springtail (Hypogastrura sp., Hypogastruridae, Collembola) and one species of beetles (Anomala corpulenta Motsch, Rutelidae). These pollinators generally have restricted movement capacities and hence promote geitonogamy or mating between individuals in close proximity within populations. The results of out crossing index pollination experiments in our study suggest that T. pingbianensis has an animal-pollinated, mixed selfing and outcrossing breeding systems.

通过对屏边开口箭的开花物候、传粉生物学、交配系统的研究以及对近交衰退的检测，结果显示：屏边开口箭单花花期约15天左右，柱头、花粉活力持续时间较长；传粉昆虫多为蚂蚁、跳虫，偶有小甲虫拜访，缺乏长距离传粉昆虫；杂交指数以及套袋试验的结果表明屏边开口箭为高度自交亲和的混交模式植物，且在幼苗早期并没有表现出明显的近交衰退现象。

Amur tigers had a copulatory pattem with no lock,thrusting, multiple intromission,and single ejaculation,which belonged to copulatory pattern No.11 in Dewsbury\'s copulatory-patterned system.5 The behaviors that accounted for most of the total time budget during the parturition period were grooming,lying and licking kittens,26.90%,26.23%and 23.83%,respectively.

东北虎的交配模式属于Dewsbury分类系统中的第11种，即无锁结、有抽动、单次插入、多次射精。5在分娩过程中，雌虎的梳理、卧息和舔仔行为时间最长，分别为26.90%、26.23%和23.83%；梳理、努责和舔仔行为发生频率较高，分别是37.95%、18.75%和12.50%。6在育幼过程中，雌虎室外期与室内期哺乳和亲仔行为的时间差异极显著(P＜0.01)，离开行为的时间差异显著(P＜0.05)。

Instead they were concerned about the putative effects of rural "degeneration" on the Nation and its food supply, as seen most glaringly in notorious stories about inbred, mentally defective families such as the Jukes and the Kallikaks.9 In order to counteract what they thought was the growing insularity, narrowness, and anarchy of rural life, they spent much of

与上述研究不同，他们关注的是假设的国家乡村"退化"的结果和食物供应问题，如臭名昭著的Jukes和Kallikaks这样的近亲交配、心理缺陷的家庭，这是个典型案例。

Another Jungle Fowl peculiarity: After mating season, males replace their bright red and orange ruff with a crop of dull, blackish feathers called "eclipse plumage."

另一个原鸡的特点是：交配季节后，公的用称为"蚀羽"的暗淡的、带黑色的嗉囊替换了自己明亮的红色和橙色颈毛

Often it is sexually selected so that scarlet markings signal male dominance.Just think of the red stripes on the scowling face of the male Mandrill, Africa's largest monkey species.

由于红色的印记代表着雄性动物的优势或支配能力，因此这些动物在交配时经常被选中，山魈的忧郁面孔上长着一块红色的标记，就是一个很好的例子。

The survival of oospores which were produced in the media was assessed after a winter. The methods promoting the oospore germination and the factors affecting the oospore germination were also investigated. Identfication of mating type, resistance to metalaxyl and isozyme genotype were performed on the F1 generations and parental isolates of oospores.

对马铃薯晚疫病菌在培养基上产生的卵孢子越冬后的存活能力、诱导卵孢子萌发的方法、影响卵孢子萌发的因素和卵孢子亲本及F_1代菌株的交配型、对甲霜灵抗性和同工酶基因型进行了初步测定和研究。

A chestnut mare, after having a hybrid by a quagga, produced to a black Arabian horse three foals showing a number of stripes - in one more stripes were present than in the quagga hybrid.

一匹栗色的母马在和一匹白氏斑马杂交之后，再与一只黑色的阿拉伯马交配产下的三只马驹身上有一些条纹，其中一只的条纹的数目比之前和白氏斑马杂交之后产下的后代还要多。

Methods: Adult mice of Kunming variety were used as experiment animals. After judgement of oestrus, the oestrus period and oestrus stage were determined, and then those mouse were grouped depending on oestrus stage. The mice were dealed with diferrent dosage of PMSG and HCG to make them superovulation, afterwords were mated individually with the male mouse together at same cage. The embryoes were rinsed out and evaluated after 3.5 days when the plug had been seen. The transplant mice were born after the high-quality embryoes were transferred into the receptors mouse uterus at the same oestrus stage which was stimulated by mating with the male mouse which spermaduct had been ligated previously.

以昆明系小白鼠为实验动物，取性成熟个体，先进行发情鉴定，确定其发情周期及不同的阶段，然后按发情阶段分组，分别用不同剂量的孕马血清促性腺激素和人绒毛膜促性腺激素进行超排处理并与公鼠合笼，在见栓后的第3.5天冲胚，对所得胚胎进行鉴定；将质量较好的胚胎选出，移入同期发情并经结扎公鼠交配刺激后见栓的受体小鼠子宫内，得到移植小鼠。

This paper presents a maximum criterion-based phylogeny analysis method for unrooted trees. To increase the confidence level of the derived evolutionary trees, we use bootstrapping and consensus analysis in conjunction with a genetic algorithm for crossover and mutation between evolutionary trees.

本论文采用最大概率字元特徵式的评分方式，以及无根的建构方法，利用基因演算法对所有可能的树的子树做交配与突变，再使用统计自序法与一致演化树法来增加树的可信度。

The Shetland Sheepdog, like the Collie, traces to the Border Collie of Scotland, which, transported to the Shetland Islands and crossed with small, intelligent, longhaired breeds, was reduced to miniature proportions.

喜乐蒂牧羊犬与柯利牧羊犬非常相象，其血统还可以追述到苏格兰边境牧羊犬流落到喜乐蒂岛的时期，当时，苏格兰边境牧羊犬与体型较小的、聪明的、长毛型犬交配，并得到缩小比例的品种。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
