卵子

When mating , the female deposits her eggs into his pouch , and the male fertilizes them internally .

当交配时，雌性存放她的卵子到他的小袋，和雄性使肥沃它们在内部。

Only one sperm fertilizes an egg.

只有一个精子使卵子受精。

The male sperm fertilizes the female egg.

雄性的精子使雌性的卵子受精。

This means that when the sperm containing one allele of each gene fertilizes the egg containing one allele of each gene , then the offspring will once again have two alleles for each gene .

这就是说，意味着每个精子和卵子各包含一份遗传基因，这样他们的后代在染色体基因位置上包含来自其父母的两种基因。

In the coming month, his belly will begin to secrete a kind of liquid that moisturizes the fertilized eggs.

在未来的一个月里，它的腹部会渗出液体，滋润受精卵子。

So it is pure chance whether the sperm and the egg carry the mutated gene or the normal one.

所以这是纯粹的机会，是否精子和卵子进行基因突变或正常1。

In the female, ER was distributed in the nucleus of oogonia cytoplasm and membrane of early primary oocytes.

因此，可以认为雌性激素ER结合唤醒了&休眠&的卵原细胞和精原细胞，细胞核发生一系列成熟分裂期的变化，从而启动了卵子和精子发生的开始。

The results were as follows: nanos 1 mRNA uniformly dispersed throughout the cytoplasm of oocytes at all stages. Strong expression of nanos1 mRNA was observed in oogonia and stageⅠ、Ⅱ oocytes, but the signal became weaker in later stage oocytes.

结果表明：在斑马鱼卵子发生中，nanos1 mRNA均匀分布于卵原细胞和各时期卵母细胞的胞质中；在卵原细胞和Ⅰ、Ⅱ期卵母细胞中，nanos1 mRNA的杂交信号十分强烈，而较晚期卵母细胞中信号明显减弱。

The results showed that Golgi complex was an organelle that experienced a series of changes during four stages of the oogenesis of Bullacta exarata , which were oogonia, early vitellogenic oocyte, mid-vitellogenic oocyte and end vitellogenic oocyte.

结果表明，在泥螺卵子发生的四个时期即卵原细胞期、卵黄发生早期、卵黄发生中期和卵黄发生后期，卵母细胞内高尔基复合体经历了一系列的变化。

We have concerns regarding the risk of stimulating ovaries to produce more eggs," she said."

我们对刺激卵巢产生更多卵子带来的风险有很多顾虑，&她说。&

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
