不减数分裂

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。

In addition, some abnormal cytology behaviors, such as univalence, multivalence, chromosome bridges, lagging chromosomes, non-equivalent division, and micro-nucleus, etc. were also observed in the meiosis of pollen mother cell.

在杉木花粉母细胞减数分裂过程中观察到一些异常细胞学行为，即单价体和多价体、染色体桥、滞后染色体、不均等分离、微核等异常现象。

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。

Aneuploidy The condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number.

非整倍性：在减数分裂的过程中同源染色体不分离而造成的一条或多条染色体的缺失或增加。

Autopoly-ploids may arise from the fusion of diploid gamete s 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。你知道它的英文吗？

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。

The time at which the two reductive divisions occur is not necessarily coincident to the time of ovulation.

两次减数分裂的时间不一定与排卵时间相一致。

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。

Cloning of spermatogenesis related genes and further functional study are very important to the elucidation of molecular mechanism involving in spermatogenesis and spermiogenesis process.

克隆睾丸精子发生相关基因并研究其功能，对于揭示精子发生过程中减数分裂和变态的分子机制，对于临床男性不育的诊断和治疗以及男性分子节育等均具有重要的意义。

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。
