During telophase I of meiosis, the chromosomes decondense and cytokinesis comes to an end. Cytokinesis refers to the division of the cytoplasm, which results in two haploid daughter cells at the completion of telophase I.Know More
Meiosis I begins with prophase I, which is when the most important processes occur. During this substage of meiosis I, the chromosomes and the centrioles move to opposite sides of the cell. The nuclear membrane also begins to dissolve during prophase I. The chromosomes go through the process of "crossing over," which allows them to exchange genetic material, enhancing genetic variety.
After metaphase I and anaphase I, telophase I occurs. In some species, the chromosomes decondense during this substage. Decondensation typically does not occur if the cell undergoes rapid meiosis. At the end of this substage, there are two haploid daughter cells. Haploid means that a cell contains a complete set of chromosomes.
At the conclusion of telophase I, the cell enters meiosis II. This process consists of prophase II, metaphase II, anaphase II and telophase II. The primary difference between telophase I and II is that there are four haploid daughter cells present at the conclusion of telophase II instead of the two haploid daughter cells present at the end of telophase I.Learn more about Cells
Both mitosis and meiosis are types of cell division that share many similarities, and both share the same basic stages of prophase, metaphase, anaphase and telophase, according to the University of Illinois at Chicago. Both begin with changes in the organization of DNA in the nucleus of a cell.Full Answer >
The chromosome number is reduced during the telophase II stage of meiosis. This last of eight stages of meiosis results in the formation of four daughter cells.Full Answer >
The final result of meiosis is haploid daughter cells that have 23 chromosomes each. These haploid daughter cells may act as gametes during sexual reproduction. This includes sperm and oocytes, which can later fuse together to form a zygote.Full Answer >
Meiosis is important because it reduces the number of chromosomes by half allowing sexual reproduction to occur. If meiosis did not happen, the cell would have too many DNA pairs. This would result in the death of the cell or other life-threatening complications with offspring.Full Answer >
