Transcription: The cellulose that forms the cerebral bibes is multiplied by a process known as mitosis in which the cellulose passes through the brain, the metasploit, the anal and the telophot. In this way, the cellulose is connected with the chromosome. This general scheme does not apply to the sexual celles or the gametes and this is forming a particular process known as meiosis. This consists of two divisions that tell the consecutive cells with inter-cambio of genetic material. Each cell has to have four gametes that have every one limit of the initial chromosome.
