Mitosis vs Meiosis • Both forms of cell division • Both follow IPMAT • Mitosis – a single division of a cell that results in two genetically identical daughter cells • Mitosis produces new cells, repairs damaged body parts and replaces old, worn out cells • Less than 1% of your body cells go through mitosis at any one moment • Average time: 6 – 8 hours for human cells Mitosis vs Meiosis (con’t) • Meiosis – consists of two cell divisions that result in four cells • Each new cell only ha½ the number of chromosomes as the original cell • Meiosis only occurs in sex organs during the production of gametes (sex cells) • Mitosis can occur in any body cell Meiosis • Cells in male testes are Diploid – produce Haploid sperm cells… • Cells in female ovaries are Diploid – produce Haploid egg cells… • In humans : diploid # is 46 chromosomes Egg (23) = Zygote (46) • Sperm (23)+ Diploid number of chromosomes • Knowing the chromosome number can be useful in wildlife studies (can identify species by DNA samples of hair, scat, etc.) • 46 – humans, Sable Antelope • 44 – dolphin, rabbit • 48 – chimpanzee, orangutan, potato • 78 – dog, coyote, wolf, chicken • 38 – cats, pig, sea otter Mitosis Meiosis Most living body cells Only cells of testes/ovaries Interphase A B Diploid Interphase A B Diploid C D C D DNA Replication DNA Replication Tetrad A•A Metaphase B•B MetaphaseI A•A B•B Homologous C•C chromosomes C•C D•D D•D Cytokinesis I Cytokinesis A•A Metaphase IIB•B A B A B C•C D•D C D C D Cytokinesis II Diploid Daughter Cells A C A C B D B D
