Introduction on meiosis called reduction division:
Meiosis can take place in all kinds eukaryotic cells. For example when a cell with 8 chromosomes gets split by meiosis, it will create just 4 chromosomes in each of the new little girl cells. The major stages of division in meiosis are known as stages of meiosis department 1 as well as 2. Description to Meiosis 1 or first meiotic division:
Meiosis 1 or first meiotic department: In the very first meiotic department, both homologous chromosomes, of each set different from each other as well as go to separate little girl cells. This decreases the variety of chromosomes from diploid to haploid problems. The four stages of this division are called prophase-1, metaphase -1, anaphase -1, and also telophase -1. At prophase-1, chromosomes inherit from each moms and dad kind pair. This pairing is synopsis and is done only by homologous chromosomes. After that by a vital process called going across over or recombination. Certain pin fibers obtain connected with the centromeres of chromosomes. In this department, both chromatid of each chromosome different from each various other as well as go to separate daughter cells. With the outcome the variety of chromosomes continues to be the like produced by meiosis 1. Meiosis 2 is consequently referred to as homotypic division. The four stages of this division are
Prophase -II: when there is no interkinesis, the telophase -1 spindle, as mentioned above is changed by 2 new spindles and the centrioles and also asters, if present, replicate as well as one duplicate of each comes to lie at each post of new pin. Chromosomes, each consisting of 2 chromatids, show up in the core. The chromatids of each chromosome are signed up with at their kinetochores by chromosomal mini tubules prolonging from the contrary poles of the pin as in mitosis. Anaphase- II: the two chromatids of each chromosome different and transfer to the contrary poles of the pins. This quantity is 1/4 th of DNA existing in the original cell which went into meiosis. This produces 2 nuclei.
