补充资料：卵裂
| 卵裂 cleavage 动物的受精卵或单性发育的卵，不经过间期，在基本上不增加总体积情况下的连续细胞分裂。
卵裂所产生的各代子细胞，称为分裂球。每一次卵裂时细胞核的表现虽然和一般的有丝分裂相似，但是分裂完成之后分裂球不生长。因而核、质的比值从小变大。直到核和质的比值与这种动物的体细胞的比值相同时，分裂球便开始生长，进行一般的细胞分裂。 在卵裂过程中不仅DNA合成快，而且已知在有些动物中，卵裂无G1期。因此两次分裂之间的时间比成体细胞的短得多。卵裂速度由卵质决定，但与环境温度有关，温度高，卵裂较快。卵裂的另一特点是卵质中物质的相对空间位置，即在卵裂前和裂后所有分裂球整体的物质分布基本一致。 卵裂类型受卵所含卵黄的多少和分布情况的直接影响。①全裂。卵黄少而分布均匀的卵，分裂面可将卵完全分割开，称全裂。全裂又可根据分裂球排列的形式，分成辐射型、螺旋型、两侧对称型、两轴对称型、混合型和不规则型等6种类型。②不全裂。又称偏裂。卵黄多而集中的卵，分裂面则不能将卵完全割开。不全裂又可分为两个类型：一类是盘状卵裂，卵裂仅在动物极的胚盘上进行，胚盘下的大量卵黄部分不分裂，如软体动物中的头足类、软骨鱼、硬骨鱼、爬行类和鸟类；一类是表面卵裂，卵黄集中于卵的中央，最初几次卵裂只是细胞核在卵黄里的原生质岛中进行，细胞核达到一定数目，进入卵黄四周的卵质中，在表面继续进行分裂，如昆虫。 |
