减数

Maxillary teeth were retracted,and the overjet and overbite were adjusted to right relations,and soft convex tissues face type was improved.

上颌牙齿前突减数矫治，有助于上颌和上牙弓的突度减小，使软硬组织面型之间的形态结构一致，特别对上牙弓突度的改善是肯定而持续的。

In meiosis, the association of four homologous chromatids seen during the pachytene stage of prophase.

减数分裂前期的粗线期中，四个同源的染色单体向联系形成的结构。

Second, it is successful to try applying the dripping method of suspended cells obtained by enzyme treatment instead of traditional method for pachytene chromosomes preparation.

第二，改变普遍采用的粗线期染色体制备的传统方法，尝试用酶解滴片法制备了水稻减数分裂染色体，获得了成功。

Pachytene in MEIOSIS ,the stage in mid-prophaseⅠ that is characterized by the contraction of paired homologous chromosomes.

粗线期：减数第一次分裂前中期中的一个阶段，以配对同源染色体浓缩为特征。

Pairing of homologous chromosomes commences at one or several points on the chromosome and is clearly seen during PACHYTENE of meiosis I.

同源染色体两两成对平行靠拢，这一现象也称联会，联会发生在染色体的一点或多点上，可以在减数第一次分裂的粗线期观察到。

In case one,his testicular histology was normal and there were 20% abnormal pachytene spermatoeytes,showing unsynaptic and broken SCs.

患者2的几乎100%生精细胞被阻断在减数分裂的前期阶段，显示联会异常如SC粉碎化、SC侧生组分膨化等现象。

In this study, we performed sequential combined PI and DAPI staining and FISH with two different 45S rDNA clones on meiotic pachytene and mitotic metaphase chromosomes in tomato.

采用CPD染色对番茄减数分裂粗线期和有丝分裂中期染色体进行了显带分析，随后用两种不同的45S rDNA 克隆在相同的分裂相进行了荧光原位杂交定位分析。

The authors proposed that heterochromatin change in genome might play an important role in balancing the germplasms between maize and its distant relatve after cross and parthenocarpy.

这种变异不仅存在于表型不稳定的早代孤雌系中，而且还存在于表型稳定的高代系中，造成这种变异的原因可能是因为远缘种质的引入影响到遗传平衡进而引起染色体发生结构重排并引起染色质的变化，这种变化与玉米染色体组中非同源染色体间存在的同源片段和因此造成的减数分裂过程中非同源染色体配对有着直接的关系。

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。

Among these were one case with double mutations (D21S11 and PentaD) and another case with two different mutations (D7S820 and D16S539) in t...

在3764次减数分裂中，15个STR位点共观察到有72例突变，突变率为0 。128 %±1 。104×10-3.vWA和D21S11的突变率最高(0·292 %)，TH01和TPOX位点没有发现突变。

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。
