Abstract: Fertilizated eggs of abalone \%Haliotis discus\% Hannai were treated with cytochalasin B, cafeine and 6 dimethylaminoparine (6 DMAP) to block polar body Ⅰ, and the separated chromosomes of control and experimental groups were analysed. The results shows that the fertilized egg in the control group has 18 chromosomes and extrude 2 polar bodys after meiosis Ⅰ and Ⅱ. The development of fertilized egg was remarkably asynchronous. The special types of chromosome segregation were observed in the treated groups during meiosis Ⅱ i.e.: tripolar segregation, united bipolar segregation and separated bipolar segregation. The paper preliminarily analyzed mechanism and effect of the 3 types medicine on blocking PBI.
