miosis Most plant and animate being cubicles be diploid. The stipulation diploid is derived from the Greek diplos, meaning fork-like or deuce; the marge implies that the stalls of plants and animals leave 2 sets of chromosomes. In homosexual carrells, for example, 46 chromosomes be organized in 23 pairs. Hence, human cellular telephones atomic number 18 diploid in that they have ii sets of 23 chromosomes per set. During provokeual reproduction, the sex cells of upraise organisms unite with atomic reckon 53 another(prenominal) and form a fertilized formal cell. In this situation, all(prenominal) sex cell is a gamete. The gametes of human cells are haploidic, from the Greek haplos, meaning exclusive. This pre narrow implies that apiece gamete contains a individual(a) set of chromosomes23 chromosomes in humans. When the human gametes unite with one another, the original diploid condition of 46 chromosomes is reestablished. Mitosis then brings more or less the development of the diploid cell into an organism. The b enunciate by which the chromosome material body is halved during gamete formation is light reflex. In meiosis, a cell containing the diploid number of chromosomes is converted into quatern cells, each having the haploid number of chromosomes. In human cells, for instance, a procreative cell containing 46 chromosomes yields cardinal cells, each with 23 chromosomes. Meiosis progresss by a serial of locomote that resemble the steps of mitosis.

both major phases of meiosis occur: meiosis I and meiosis II. During meiosis I, a single cell assigns into two. During meiosis II, those two cells each divide again. The same demarcating phases of mitosis take mark in meiosis I and meiosis II. As shown in interpret 1 , first, the chromosomes of a cell duplicate and thoroughfare into two cells. The chromosomes of the two cells then separate and pass into four daughter cells. The parent cell has two sets of chromosomes and is diploid, while the daughter cells have a single set of chromosomes each and are haploid. Synapsis and crossbreeding over occur in the Prophase I stage. | | | | | | run into 1 | The...If you want to bum a full essay, order it on our website: Orderessay
