Compare and Contrast Mitosis and Meiosis

Meiosis and mitosis describes the process by which cells divide,
either by asexual or sexual reproduction to produce a new organism.
Meiosis is a form of cell division that produces gametes in humans
these are egg cells and sperms, each with reduced or halved number of
chromosomes. The number of chromosomes is restored when two gametes
fuse together to form a zygote. A cell with two copies of each
chromosome is called diploid cell and a cell with one copy of each
chromosome is called a haploid cell. Meioses produces haploid daughter
cells that are genetically different from each other and from the
parent cell. However, mitosis is a form of cell division that produces
daughter cells identical to the parent during repair or growth. Each
cell contains the same genetic code as the parent cell, it is able to
do this because it has copied it?s own chromosomes prior to cell
division. Meiosis consists of two divisions whilst mitosis is followed
in one division; both these processes involve the stages of
interphase, prophase, metaphase, anaphase and telophase.

Meiosis allows cell variation and genetic differences between each
cell whereas mitosis is an exact replication of each cell. There are
three main ways meiosis produces genetic variation, this through
independent assortment, crossing over and random fertilization. During
the first meiotic division in prophase I the homologous chromosomes
join together to form biv... [to view the full essay now, purchase below]
