查询词典 gametes

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。

Either of two conjugating gametes that differ in structure or behavior, such as the small, motile male spermatozoon and the larger, nonmotile female ovum.

异形配子在结构或行为上不同的两个配合配子之一，如小的能动的雄性精子与大的不能动的雌性卵子

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。

As with the male gametes the remaining cytoplasma binding serves the synchronization of the division and maturation of the cells: just as for the 1rst polar body at the time of the termination of the 2nd meiosis.

和雄性配子一样，这些残留的细胞质连接有助于细胞分裂和成熟的同步化：就像第二次减数分裂结束时的第一极体一样。

The growth of oocytes is faster at higher temperatures and longer daylength. There is an effect of low temperature on the gametogentic cycle and synchronous mature of gametes of the sandworm.

野外调查和室内实验结果都表明，种群卵细胞发育的起点温度为5℃；环境水温的低温效应对沙蚕生殖周期和卵母细胞同步性成熟具有深刻影响。

Self-fertilization involves male and female gametes produced by the same, hermaphrodite individual, Self-compatibility is a means by which sessile and less mobile organisms' such as plants, that are unable to actively seek mates, insure against failure to cross=fertilize.

自体受精是雌雄同体的个体同时产生雌雄配子。对于营固着生活和运动能力很弱的生物，例如植物，它们不能主动地寻找配偶，自我兼容性是确保其不发生异体受精的一种方法。

Self-fertilization involves male and female gametes produced by the same, hermaphrodite individual, Selfcompatibility is a means by which sessile and less mobile organisms' such as plants, that are unable to actively seek mates, insure against failure to cross=fertilize.

自体受精是雌雄同体的个体同时产生雌雄配子。对于营固着生活和运动能力很弱的生物，例如植物，它们不能主动地寻找配偶，自我兼容性是确保其不发生异体受精的一种方法。
