Image caption Bridge is played by four players who form two partnerships and involves predicting the number of tricks each side will win. Bridge players who wanted the popular card game recognised as a sport have lost their High Court battle.
Meiosis occurs in diploid cells. The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the chromosome number of the parental cell. Meiosis occurs only in sexually reproducing organisms.
Meiosis is a key event of the sexual cycle in Eukaryotes. It is the stage of the life cycle when a cell gives rise to two haploid cells (gametes) each having half as many chromosomes. Two such haploid gametes, arising from different individual organisms, fuse by the process of fertilization, thus completing the sexual cycle. Meiosis is ubiquitous among eukaryotes.
