减数分裂的

According to the ultrastrucral observation of PMCs, three successively specific phases could be distinguished as leptotene, zygotene and pachytene in early prophase Ⅰ of Arabidopsis.

通过对拟南芥菜减数分裂前期花粉母细胞的形态学观察，我们认为在早前期Ⅰ中，拟南芥菜又可以分为三个时期：细线期、偶线期和早粗线期。

Each megaspore mother cell, which ultimately undergoes meiosis, giving rise to a linear series of four megaspores.

每 megaspore 母亲细胞，最后接受减数分裂，引起线连续的四 megaspores。

Ovule development began in August, and rectangle megasporocyte began to occur in December, and linear tetrads of megaspores were formed in meiosis. In most occasions, only the chalazal megaspore was functional.

云南红豆杉胚珠从8月开始发生，大孢子母细胞12月开始发生，呈方形，减数分裂后形成4个"一"字形大孢子，在大多数情况下，只有靠合点端的大孢子发育为功能大孢子。

In addition, they need to come from the Y chromosome genes can be achieved meiosis.

此外，它们需要来自Y染色体的基因才能实现减数分裂。

This result indicated that the possibility of meiosis might exist in fluconazole treated system.

这暗示著白色念珠菌可能在Fluconazole处理的环境下进行减数分裂。

A group of four cells formed as a result of meiosis in a spore mother cell.

四分体：1由孢子母细胞减数分裂产生的一组四个细胞。

Aneuspory The production of an unusual number of spores during meiosis of a spore mother cell.

异数孢子：在孢子母细胞减数分裂过程中产生不正常孢子数目的现象。

Autopoly-ploids may arise from the fusion of diploid gametes that have resulted from the NONDISJUNCTION of chromosomes at meiosis.

同源多倍体通常可能来自在减数分裂过程中染色体不分离导致的二倍体融合。

It also led to the discovery in 1916 by Calvin Bridges of the phenomenon of nondisjunction, in which a chromosome pair fails to segregate during meiosis.

伴性遗传又导致了不分离现象的发现，即在减数分裂中，染色体对不分离。

Another form of apomixes in which seeds develop from unfertilized gametes can also be termed parthenogenesis.

以这种方式产生的种子不是单倍体就是二倍体，完全取决于大孢子母细胞是否经历减数分裂。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
