Production of yolk in the egg supplies the necessary fuel for the first few rounds of division of the zygote . 为了合子头几次分裂的需要，卵的卵黄产物提供必要的能量。
Distinct layers are often visible in thick-walled resting cells such as chlamydospores or zygotes of phycomycetes . 在厚壁休眠细胞如藻菌纲的厚孢子或接合子中明显的几层是常常能看见的。
How does a zygote differ from an ovum 受精卵和卵细胞有何不同
The stages of development for a baby are zygote, embryo, and fetus 婴儿的发育阶段有受精卵、胚胎、然后是胎儿。
During the process of fertilization a zygote with the diploid set is produced 通过受精作用使受精卵形成一个二倍体。
Murine zygotes are more sensitive to commonly-used fertilization culture media 小鼠合子对常用人体外受精培养液敏感性较高
Embryogeny ( embryony ) 1 . the development of an embryo from the moment the zygote divides 胚胎发生（胚状体）：1.是从受精卵分裂开始的胚胎发展过程。
The head of the sperm cell and the nucleus of the egg cell then unite and form a new cell : the zygote 然后，精子的头和卵子的核融合，形成一个新细胞：受精卵。
For example, in the development of the plant embryo from the zygote, one end becomes the radicle, the other gives rise to cotyledons 例如植物由合子到胚的发育，一端形成胚根，另一端成为子叶。
Two diploid gametes may fuse to give a tetraploid zygote, or gamete may develop directly by parthenogenesis 两个二倍体配子融合可能产生一个四倍体合子，这样的配子也可以通过孤雌生殖直接发育而来。
