采用 DAPI染色显微荧光方法 ,连续观察了虾夷扇贝×栉孔扇贝的正反交受精细胞学过程。无论正交或反交 ,精子均可正常入卵 ;受精卵能顺利完成第 1次、第 2次减数分裂 ,排出第一、第二极体 ;精子和卵子内的各一套染色体融合后 ,形成二倍体的合子进入正常的细胞分裂 ,其发育过程同母本 Using DAPI staining microscopic fluorescence method, the reciprocal cross fertilization cytology of Echinochloa scallop × Chlamys farreri was observed continuously. No matter orthogonal or anti-cross, the sperm can be normal into the egg; fertilized eggs can successfully complete the 1st and 2nd meiosis, excretion of the first and second polar body; sperm and egg within a set of chromosome fusion , The formation of diploid zygotes into normal cell division, its development process with the female parent
