Meiosis (my-OH-sihs) is a form of nuclear division that divides a diploid cell into haploid cells. This process is essential for sexual reproduc-tion. The details of meiosis will be presented in the next section. But FIGURE 6.2 highlights some differences between mitosis and meiosis in advance to help you keep these two processes clear in your ...

Meiosis 1 Meiosis How does sexual reproduction lead to genetic variation? Why? Cells reproduce through mitosis to make exact copies of the original cell. This is done for growth and repair. Sexually-reproducing organisms have a second form of cell division that produces reproductive cells with half the number of chromosomes.

Meiosis is part of the sexual process because gametes (sperm, eggs) have one half the chromosomes as diploid (2N) individuals. Phases of Meiosis There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell.

2 are in the right daughter cell. This marks the end of meiosis 1. At the e,nd of meiosis I, the chromosome pair has separated and a chromosome that onsists of two sister chromatids has moved to 'ach daughter cell. The sister chromatids are held together at the centromere. Each of the two daughter cells will now enter meiosis

This time, the Meiosis I results in two cells, each containing both genes (1 tan, 1 wild-type); therefore, the genes for spore color have not yet segregated. Meiosis II results in segregation of the two types of genes for spore color. A mitotic division results in 8 spores arranged in the 2:2:2:2 or 2:4:2 pattern.

cell. This is not the case for meiosis, which reduces the chromosome number by half. Mitosis results in the production of two genetically identical diploid cells, whereas meiosis produces four genetically different haploid cells. Mitosis is a form of asexual reproduction, whereas meiosis is an early step in sexual reproduction.

Two of the most noted differences in meiosis are that 1) there are two complete divisions resulting in four daughter cells and, 2) meiosis has crossing over, an even that occurs in Prophase I that increases genetic variation in the gametes. Crossing over occurs between homologous chromosomes. These are

Connexions module: m44469 2 1 Meiosis I Meiosis is preceded by an interphase consisting of the G 1, S, and G 2 phases, which are nearly identical to the phases preceding mitosis. The G 1 phase, which is also called the rst gap phase, is the rst phase of the interphase and is focused on cell growth.
