Fig. 1. Standard dimorphic or trimorphic reproductive cycle in benthic, medium- to large-sized foraminifera according to Goldstein, 1999. Schizogeny, eventually repeated several times, may be widespread in larger foraminifera from oligotrophic habitats. Planktic foraminifera seem to have no dimorphic life cycle. Life cycles are linked in various ways to seasonal cycles. Example: Heterostegina depressa d'Orbigny, equatorial sections, Gulf of Aqaba, Red Sea (from Hottinger, 1977); (Hottinger, 2006; fig. 5 [1] CC/BY-NC-SA)

Definition

  • according to Hottinger (2006):

MEIOSIS (reduction division) – step in the process of cell division, during which the chromosomes of the parent cell are reduced from a double to a simple set (from diploid to haploid) for each daughter cell.
