查询词典 zygote

Tetraploid organisms may arise by the fusion of two diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis, or by nondisjunction of the chromoosomes during the mitotic division of a zygote.

四倍体的产生可能是由于两个二倍体配子发生融合，这种二倍体配子又是在减数分裂中染色体不发生分离而形成。四倍体也可能因为受精卵进行有丝分裂时染色单体未发生分离而形成。

After zygote dividing,the degeneration of nucellusgains the upper hand,and almost all nucellus cell disappear in 4-5 days after flowingexcept for the most outside nucellus.

合子分裂以后则以退化为主，到开花后4-5天，珠心组织除了表皮细胞外，其他几乎都解体了。

Most of them probablyoriginated from the zygote,and minority do from early parthenogenesis.

这些胚胎多数可能是经过受精发育而来的，极少数可能来自早期的单性生殖。

Paternally derived FAC1 gene is expressed at the zygote stage, which counts as the earliest paternally expressed gene known in plants.

父源的FACl基因的表达在合子中即可被激活，这是已知的最早表达的父源基因。

At fertilization one male nucleus fuses with the gee nucleus to form the zygote, while the second male nucleus fuses with the primary endosperm nucleus to form a triploid cell, or more rarely a second diploid or a pentaploid cell that later gives rise to the ENDOSPERM.

受精作用发生时，一个精核与卵核融合形成受精卵，第二个精核与最初胚乳核融合，形成三倍体细胞，偶而也形成第二个二倍体或五倍体细胞，三倍体细胞最后发育为胚乳。

Double fertilization The fusion of one pollen nucleus with the egg to form the zygote and of the other pollen nucleus with a polar nucleus to form the triploid endosperm nucleus.

双受精：指花粉粒中的一个精子与胚珠中的卵细胞结合形成受精卵，另一个精核与极核结合形成三倍体的胚乳核。

Results 1 Hypergravity influenced early development of zebrafish from zygote to early larva, and otolith size significantly larger in the early stage (P.01) but decreased subsequently. 2 Examined with EDAX, the contents of sulfur and Sr increased while Ca and Na contents decreased. 3 It was observed that sagitta and lapilli otoliths were fused into one otolith.

结果 1斑马鱼从鱼卵向早期仔鱼发育过程中超重环境影响仔鱼发育，耳石形态在初期显著变大(P.01)，其后耳石变小；2EDAX检测表明，耳石中S和Sr含量升高，Na和Ca的含量减少；3出现矢耳石与微耳石融合的现象。
