WebThere is no meiosis and no nuclear fusion in this process. In cytogamy, two paramecia form a pair in a way similar to conjugation. However, there is no nuclear exchange between individuals. Two haploid gamete nuclei in each cell fuse within the original cell. The individuals now separate and divide.
