Compare and Contrast Mitosis and Meiosis Essay -- Biology

Comp ar and Contrast Mitosis and MeiosisMeiosis 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 humansthese are egg cells and sperms, individually with reduced or halved number ofchromosomes. The number of chromosomes is restored when two gametesfuse together to form a zygote. A cell with two copies of from each onechromosome is called diploid cell and a cell with one copy of eachchromosome is called a haploid cell. Meioses produces haploid daughtercells that are patrimonialally different from each other and from theparent cell. However, mitosis is a form of cell division that producesdaughter cells identical to the parent during repair or growth. Eachcell contains the same genetic code as the parent cell, it is able todo this because it has copied its own chromosomes prior to celldivision. Meiosis consists of two divisions whilst mitosis is follow edin one division both(prenominal) these processes involve the stages ofinterphase, prophase, metaphase, anaphase and telophase.Meiosis allows cell variation and genetic differences between eachcell whereas mitosis is an exact replication of each cell. There arethree main ways meiosis produces genetic variation, this throughindependent assortment, crossing over and random fertilization. Duringthe first meiotic division in prophase I the homologous chromosomes nub together to form biv...
