To achieve the reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division. figure section4.1.4 s e c t i o n 4.1. 4: an overview of meiosis. two sets of homologous chromosomes are shown. one set is comprised of a long red and a long blue chromosome.

File Meiosis Diagram Jpg In biology, meiosis is the process where a cell replicates dna once but divides twice, producing four cells that have half the genetic information of the original cell. it is how organisms produce gametes or sex cells, which are eggs in females and sperm in males. in meiosis one cell divides twice, forming four cells. Mitosis of that first cell gives rise to clones that make up the rest of the organism’s body. maintenance: some examples: skin cells slough off, rbc’s live 3 months, intestinal cells divide rapidly to replace older cells. repair: damaged cells ranging from skinned knees to post surgical healing is repaired by mitosis. Outcome. while mitosis yields two daughter cells that are genetically identical (2n) to the parent cell, meiosis produces four haploid (n) cells that are genetically different from the parent cell. mitosis: two identical daughter cells. meiosis: four non identical daughter cells with half the chromosome number. Meiosis i: this is also referred to as the reduction division in which the chromosome content of the daughter cell is reduced to half of that of the mother cell. as in mitotic division, meiosis i is preceded by replication of the dna content of the dividing cell. the first phase of meiosis i is the prophase. this goes through 5 stages as follows:.

The difference between the two processes is that mitosis occurs in non reproductive cells, or somatic cells, and meiosis occurs in the cells that participate in sexual reproduction, or germ cells. you can navigate to specific sections of this handout by clicking the links below. mitosis: pg. 1 meiosis: pg. 4 mitosis vs. meiosis: pg. 7. Comparing meiosis and mitosis. mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. they share some similarities, but also exhibit a number of distinct processes that lead to very different outcomes (figure 11.8). mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two.
