减数

The basidioma is composed mainly of sterile tightly packed hyphae; in most species there is a distinct fertile layer, the hymenium, on the surface of the basidioma that bears the basidial hyphae which, after meiosis, give rise to the basidiospores.

担子果主要由紧密缠绕的不育菌丝组成，多数种类还有明显的可育层子实层，子实层位于担子果的表面，由菌丝形成担子，减数分裂后产生担孢子（参见 basidium

In skin lesions and their margins,characteristic hyperkeratosis of epidermis and hypertrophy of sebaceous glands were observed,which were not found in the wild-type mice.

其中A族有两种形态，一种只表达于减数分裂和非常早期胚胎的胚胎特异型cyclin A1，和一种在体细胞中都可以见到的体细胞型cyclin A2。

Few studies have been conducted so far on meiotic progression and none was carried out on its control via hypoxanthine in goat oocytes.

但是，有关山羊卵母细胞的减数分裂进程及其调控均有待进一步的研究。

Centromere The region of the chromosome that contains the kinetochore, the structure that becomes attached to the nuclear spindle during mitosis and meiosis.

着丝粒：染色体上包含着丝点的区域，在细胞有丝分裂和减数分裂期间与纺锤体相整合的一种结构。

Here we show that the inner nuclear membrane protein SUN1 specifically associates with telomeres between the leptotene and thediplotene stages during meiotic prophase I.

我们发现内核膜蛋白SUN1从减数分裂前期Ⅰ的细线期到终变期，特异性的与染色体端粒相结合。

At the leptotene stage the enzyme was mainly present in the cisternae of smooth endoplasmic reticulum and their derived vesicles, but absent in the Golgi body and Golgi vesicles.

花粉母细胞减数分裂前期Ⅰ的活性进行了电镜细胞化学定位，以研究其在次生胞间连丝和胞质通道形成中的作用。

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。

Patients undergoing cytoreductive surgery combined with intraperitoneal chemotherapy are required to be in the lithotomy position for many hours.

At this time, meiosis has not yet occurred in the megasporangium.

在这次，减数分裂在大孢子囊中还没有发生。

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。

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。
