二倍性

Protein and triglyceride content in adductor muscle increased during gametogenesis, and then deceased in spawning.

在非繁殖期二倍体和三倍体性腺和闭壳肌生化成分含量受倍性影响不大。

Study on the pollen fertility and the process of pollen formation and development in autotetraploid rice showed that the pollen fertility was high (78.33%), though many abnormities appeared in this process.

通过对5个品种的同源四倍体水稻花粉发育过程和13 个品种的花粉育性调查结果表明，同源四倍体花粉平均育性为78.33%，明显比二倍体（91.85%）低。

Results DNA analysis showed that almost all the CISs and EMICs were diploidy , while 90% of invasive carcinomas were aneuploidy.

结果 DNA倍体分析表明CIS、EMIC和浸润性癌不同，前两者几乎都是二倍体，而后者 90 %为异倍体

Fig 1 The results of two color FISH A:Normal sperms(a sperm nucleus with a red fluorescence domain was X sperm, and with a green fluorescence domian was Y sperm);B:Numeric chromosome abnormal sperm two green fluorescence domains within the same sperm nucleus which may be classified in Y disomic sperm or diploidy sperm, in the case of hybridization with two probes, one euchromosome specific and the other sex chromosome specific, this sperm could be discriminated as disomic or diploidy sperm

图1 双色荧光原位杂交结果 A：正常精子(精子头部有1个红色荧光信号者为X精子，有1个绿色荧光信号者为Y精子)；B：染色体数目异常精子两个绿色荧光信号同在1个精子核内，可为Y双体精子或二倍体精子，若用1条常染色体探针和1条性染色体探针进行双色荧光原位杂交，可以区别该精子属Y双体精子或二倍体精子

By using two color FISH with one euchromosome probe and one sex chromosome probe, the sperm with same color of two hybridization signals in one sperm head could be identified as aneuploidy sperm or diploid sperm.

若用1条常染色体探针和1条性染色体探针进行FISH，可以区别头部有2个相同颜色荧光杂交信号的精子属非整倍体精子或二倍体精子。

Results The p53 gene mutation rate of colorectal cancer was 50%. The rate of apoptosis of tumor cells having mutation of p53 gene (22.11%) was much lower than that having no p53 mutation (40.57%, P＜0.05). Heteroploid cells had been found in 10/13 tumor samples with p53 gene mutation and 6/13 samples without p53 mutation (P＜0.05). The rate of apoptosis had no difference between the heteroploid cases and diploid cases.

结果 大肠癌标本p53基因突变率为50%；其中突变组肿瘤细胞凋亡率(22.11%)明显低于未突变组细胞凋亡率(40.57%)，(P＜0.05)；突变组异倍体细胞百分率(占76.9%)明显高于未突变组(占46.2%)，(P＜0.05)；异倍体肿瘤细胞凋亡率为34.0%，二倍体肿瘤细胞凋亡率为40.7%，二者差异无显著性(P＞0.05)。

Polymorphism in diploid species G.arboreum was the same as in tetraploid species G.hirsutum,both were 11.84%.

在二倍体棉种中棉的扩增多态性率为11.84%，与在四倍体棉种陆地棉的扩增多态性率相同。

However, analysis of DNA methylation level indicated that the total DNA methylation levels were not significantly different between diploid and autotetraploid. Autotriploid showed a trend of low DNA methylation level. It implied that the alterations of DNA methylation levels were not linear with the autopolyploidy level in watermelon.

有趣地是，二倍体与四倍体西瓜相比DNA甲基化水准却未发生大规模的调整，而三倍体西瓜显示出较为明显的低DNA甲基化水准趋势，表明西瓜同源多倍化过程中其基因组DNA甲基化水准变化与其倍性不成线性关系。

The improved L.D.Cua method was used to induce tetraploid of Trichosanthes kirilowii Maxim. The suitable treating time of 0.2% colchicine, the morphology characters and cytology identification between plants of diploid and obtained tetraploid were studied.

采用改良L.D.Cua法诱导短把栝楼获得四倍体，研究了0.2%浓度的秋水仙碱诱导短把栝楼染色体倍性变异的最佳处理时间、四倍体栝楼与原栝楼的形态特征及其四倍体与二倍体的细胞学鉴定。

"Wheats are called diploids when they have seven chromosomes, tetraploids when they have fourteen , and hexaploids when they have twenty-one."

其性细胞具有7条染色体的小麦称为二倍体；具有14条染色体的称为四倍体；具有21条的称为六倍体。

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。
