from Wikipedia, the free encyclopedia

Syngamy describes the process in which cells of the opposite sex - mostly gametes - completely fuse with one another. The term includes plasmogamy , i.e. fusion of cell plasmas, on the one hand, and karyogamy , i.e. fusion of cell nuclei , on the other . If plasmogamy and karyogamy follow each other briefly or immediately, the syngamy only lasts for a short time. If, for example, most mushrooms are far apart in time, it takes correspondingly longer, with the result in both cases usually being a diploid zygote .
