四倍体的

Methylation variations of artificial F4 and F10 generations of Raphanus sativus×Brassica alboglabra allopolyploid were examined with MSAP. The results showed that the methylation levels of F4, F10 were 30.61% and 33.10%, respectively.

以人工合成的萝卜－芥蓝异源四倍体的F4和F10世代为材料，用MSAP法检测2种材料DNA甲基化变异情况，以期为远缘杂交后不同世代间基因组DNA甲基化遗传和变异规律提供实验依据。

The autotetraploid plant of sesame may be effectively induced by immersing seeds with 0.3%-0.5%colchicine water solution under 28 ℃ for 24 hours.

在28 ℃的条件下，用0.3%～0.5%的秋水仙素水溶液浸种24 h，诱发产生芝麻同源四倍体的效果较好。

I'm afraid the details are confidential, but I treated a tetraploid man once.

恐怕细节是机密的，但是我对待了一个四倍体的男人一次。

He knew he was tetraploid, but hadn't the foggiest why, or why it had caused him to regenerate like that.

他认识，他是四倍体的，但是不有最雾深的为什麼，或它为什麼已经导致他像那一样再产生。

Apparently, every year he went through the change from one form to the other, but had only recently realized he was tetraploid, and hadn't yet figured out the connection between the two.

/ 显然地，每年他经过从一种形式到另一个的改变，但是只有最近有了解他是四倍体的，而且没有理解之间的连结那二。

Dot plot image of DNA fluorescence could form region of diploid and tetraploid in integrated cell.

结果显示：结构完整的细胞DNA的荧光点图形成二倍体、四倍体的区域。

结果显示：结构完整的细胞DNA的荧光点图形成二倍体、四倍体的区域。

This may be due to the characteristics of soybean genome,an ancient tetraploid.

这些基因位于10条不同染色体上，FT类基因具有成对排列于同一条染色体的短的区段的倾向，TFL1和CEN的4个不同拷贝均位于不同的染色体上。7对基因之间同源性高于90%，而且多位于不同染色体上，可能与大豆古四倍体的特性有关。4。

Long treatments(7–43 min — about three quarters of the period of meiosis I in triploid eggs). yielded only heptaploid cells among the embryos.

在抑制三倍体受精卵第一极体（PB1）过程中，处理时间的不同对后代四倍体的得率有明显影响。

Chloroplast size was bigger and grana stack was thicker in tetraploid than that in diploid.

四倍体的叶绿体的长度和宽度均显著高于二倍体，基粒片层加厚，结构致密有序。

And if officials on the take are not parroting the opinions of these companies, what can we suppose the money they receive is for?

如果受贿的官员不鹦鹉学舌般地复述这些公司的看法，那他们所接受的钱又能用于什么目的呢？

Love them, and love you too, Pitcher.

爱他们，也爱你，投手。
