When organisms reproduce, they pass their genetic information to their offspring. This genetic information includes genes, which are pieces of hereditary material that affect an organism's inherited traits.

WebbLa prophase, en biologie cellulaire, est une des phases du cycle d'une cellule, avec deux possibilités selon qu'il s'agisse d'une mitose ou d'une méiose. Une prophase est une étape de la mitose dans laquelle la chromatine se condense en structures doubles en forme de bâtonnets appelés chromosomes dont la chromatine devient visible. WebbMeiosis is a special type of cell division. Unlike mitosis, the way normal body cells divide, meiosis results in cells that only have half the usual number of chromosomes, one from each pair. For that reason, meiosis is often called reduction division. In the long run, meiosis increases genetic variation, in a way which will be explained later.
