The genetic inactivation of eggs is the first key stage of androgenesis in fish. In order to observe the effect of UV irradiation for the inactivation of female nucleus of zebrafish the eggs were irradiated by UV with solution-free, pure water, Ringer's solution and Cortland solution. The results showed that abnormal fry were obtained in all groups and haploids were validated. But irradiation with solution was confirmed it could not inactive fully female nucleus and the fertilization rate of the eggs irradiated with pure water was very low.

雌核灭活是雄核发育的第一个关键步骤，为研究紫外线对斑马鱼卵的雌核灭活效果，将斑马鱼的卵采用干法或置于纯水、Ringer氏溶液和Cortland鱼用生理盐水进行紫外线照射，结果表明，各种方法中均得到畸形鱼苗，并经染色体检查大多为单倍体；四种方法中在Cortland鱼用生理盐水中灭活效果最好，120 mJ/cm2紫外线可以使雌核完全灭活；干法处理不能达到雌核完全灭活的目的，在纯水中灭活后的卵子受精率较低。

There is some evidence that this process can be selective (7). A second possibility simply involves a relative selective advantage to wildtype mtDNAs during the expansion of mitochondria that occurs in oogenesis.

一些证据表明这些过程是就可以被选择的（7）；第二中可能性涉及到在卵子发生的过程中对胀大的线粒体内野生型mtDNA进行相关的优势选择。

Scientists believe Theridion grallatormay have developed its distinctive markings to discourage birds from eating it.

现在知道它唯一的模式是蜘蛛装饰其腹部呈苍白色的原因。科学家相信它是为了变苍白特色而使得气馁的鸟儿不去吃掉它和它的卵子。

In Klinefelter's syndrome however, due to one of nature's accidents, when the male sperm fuses with the female egg, the fetal cells have at least one extra X chromosome. The most common number of chromosomes found in KS is 47, that is 44 autosomes and 3 sex chromosomes giving a karyotype of 47,XXY.

在克氏综合徵，但由於一大自然的意外，当男性的精子导火索，与女性卵子，胎儿细胞有至少一个额外的X染色体是最常见的染色体数目，发现在堪萨斯州是47 ，这是44 autosomes和三性染色体给予染色体核型47 ， xxy 。

These nine principles underpin the awesome workings of prairies, flamingoes, cedar forests, eyeballs, natural selection in geological time, and the unfolding of a baby elephant from a tiny seed of elephant sperm and egg.

造物九律支撑着令人敬畏的自然运作：大草原，火烈鸟，雪松林，眼球，地质演变中的自然选择，乃至从幼小的精子卵子到幼象的演变。。。。。。

Inthe whole process, the oocytes, nurse cell and follicle cell morphology change. Inoocyte yolk formation and growth, the number of its nuclear trophoblast cell nucleoli,lamphrush chromosome with a strong synthetic material; oocytes also some syntheticmaterial; follicle cells in the yolk protein synthesis, provide access to exogenous yolkprotein.

在卵子发生的整个过程中，卵母细胞、滋养细胞及滤泡细胞形态均有明显变化；在卵母细胞生长及卵黄形成期，滋养细胞核内的多核仁现象、灯刷染色体与旺盛的物质合成有关；卵母细胞本身也合成一些物质；滤泡细胞参与卵黄蛋白的合成，并为外源性卵黄蛋白提供通道。

We have exposed that during the climax of intelligence, energy and constitution, the sperms and ovums had best qualities.

The scientists will transfer the pro-nuclei -- the components of a human embryo nucleus -- made by one man and woman into an unfertilised egg from another woman.

科学家们将把取自于一男一女受精卵的原核（pronuclei，人类胚胎细胞核的构成成分）移植到另外一名妇女提供的一个未受精的卵子中去。
