autogamy
autogamy
1. A type of reproduction that occurs in single isolated individuals of ciliate protozoans of the genus Paramecium. The nucleus divides into two genetically identical haploid nuclei, which then fuse to form a diploid zygote. The onset of autogamy is associated with changing environmental conditions and may be necessary to maintain cell vitality. 2. Self-fertilization in plants. See fertilization. |
