  • Two Separate Cells
    1,297 words
    Hi, Joe Bob's here. I'm pretty sure I last left you in the study of mitosis. Mitosis is very similar to our study today, Meiosis. Now, In Meiosis there is only one more phase for each stage of Meiosis, then Mitosis. Let's see where I'm heading first in my Magical Meiosis journey. Let Maryann tell you about the back round of Meiosis. "Well, Joe Bob! As you and me both know, Meiosis is used for producing Gametes and sex cells. Gametes are basically sex cells; egg cells are gametes, and sperm cells...
  • Stage The Chromosomes
    998 words
    Cell division may happen by either mitosis or meiosis, depending on what type of cell is. Mitosis is a process by which a cell divides to form two daughter cells. They each have the same exact number and kind of chromosomes as the parent cell. Meiosis occurs in the primary sex cells leading to the formation of viable egg and sperm cells. They reduce the number of chromosomes to half in each gamete so that when they are getting fertilized, the species chromosome number is kept even. Mitosis happe...
  • Extra Chromosome On The Chromosome 21 Pair
    547 words
    State that meiosis is a reduction division in terms of diploid and haploid numbers of chromosomes Outline the process of meiosis including pairing of chromosomes followed by two divisions which result in four haploid cells In meiosis, the number of chromosomes is halved, the daughter cells receiving only one of each type of chromosome instead of two. It occurs in the formation of gametes (sex cells). In the diploid parent cell, chromosomes occur in homologous pairs (the same size). The parent sp...
  • Animal Cells Three Different Kinds Of Chromosomes
    348 words
    Different kinds of Animal chromosomes exist with very different parts. To start, in animal cells three different kinds of chromosomes can be seen. The first kind is the X chromosome, which is one of the sex-determining chromosomes. The other sex-determining chromosome is the Y chromosome. The rest of the chromosomes are referred to as autosomes. Two different kinds of animal cells exist, male and female, each of which has a different make up of chromosomes. For example, the male fruit fly has 3 ...
  • Two Daughter Cells Following Telophase II
    319 words
    Gametogenesis begins in the seminiferous tubules of the testis, in human males. Meiosis begins with a diploid cell, spermatogonium, which divides through mitosis. The spermatogonia accumulate cytoplasm and replicate DNA. They are then called primary spermatocytes. In meiosis I, the primary spermatocytes' chromosomes undergo synapsis, in which homologous pairs of chromosomes find each other, during Prophase I. Crossing over also takes place during Prophase I. In Metaphase I, independent assortmen...
