Meiosis and its applications
What exactly is meiosis? A body cell has the same chromosomal count as its parent cell. How can sex cells get up with half as many chromosomes? Meiosis is the process through which cells divide to generate sex cells. has a chromosomal count of half that of a human. A cell divides twice during meiosis to create four sex cells, each with half the amount of chromosomes as the parent cell. Meiosis's first division The homologous pairs of chromosomes split during the first division of meiosis. Remember that chromosomes double shortly before a cell splits. The doubled chromosomal pairs align near the cell's center. Spindle fibers adhere to the pairs and pull them apart. Two cells are formed. Each cell carries one homologous pair's doubled chromosome. Meiosis's second division The doubled chromosomes are separated during the second stage of meiosis. The duplicated chromosomes align in the cell's middle. Spindle fibers separate the chromosomes in the middle.The two halves...
