If the events you are referring to are:
a. cells separate
b. disintegration of micronuclei
c. mitosis of micronuclei
d. meiosis of micronuclei
e. micronuclei fuse
f. exchange of micronuclei
If we fix this in order, the first would be mitosis of the micronuclei, then the meiosis of micronuclei, then the micronuclei breakdown. Then there conjugating cells exchange micronuclei and then they fuse. Lastly the cells separate.
The answer to the question is the cells separate.
