Mitosis/Meiosis How are they different? The exchange of DNA between the chromatid arms on homologous pairs is called ________________ Crossing over This type of cell division used by bacteria to reproduce Binary fission The mixing up of maternal and paternal chromosomes as they move apart during anaphase I is called ______________ Independent assortment The pairing up of homologous chromosomes during prophase I synapsis is called _________________ This diagram is showing _________________ Crossing over During which phase does this happen? PROPHASE I of meiosis Is it MITOSIS or MEIOSIS? mitosis Makes 2 daughter cells ______________ meiosis Makes haploid cells _______________ Divides twice but meiosis copies DNA once __________________ mitosis Used to repair injuries ______________ Is it MITOSIS or MEIOSIS? Meiosis Makes 4 daughter cells ______________ mitosis Makes diploid cells _______________ mitosis Copies DNA every __________________ time it divides meiosis Used to make gametes ______________ Is it MITOSIS or MEIOSIS? Makes 2n cells ______________ mitosis Crossing over happens _______________ meiosis mitosis Used when organisms _________________ grow bigger meiosis Used in sexual reproduction ___________ Is it MITOSIS or MEIOSIS? meiosis Testes and ovaries do it ____________ mitosis Body cells do it _______________ meiosis Crossing over happens ____________ Divides twice ______________ meiosis in a row Is it MITOSIS or MEIOSIS? meiosis Independent assortment_____________ happens mitosis Divides just once_______________ meiosis Used in oogenesis __________________ Makes cells identical to parent cell __________________ mitosis Is it MITOSIS or MEIOSIS? mitosis Makes 2 daughter cells ______________ meiosis Makes haploid cells _______________ Divides twice but meiosis copies DNA once __________________ mitosis Used to repair injuries ______________ Type of cell division shown meiosis Body organ where you would expect to see the above happen Ovary or testes Type of cell division shown mitosis Tell one reason why a cell would do this Grow organism bigger Repair injuries Replace worn out cells The small cells produced when the cytoplasm divides unevenly during Polar bodies oogenesis are called ______________ Producing offspring without using sperm or eggs in which the DNA comes from only 1 parent Asexual reproduction TRUE or FALSE Polar bodies will go on to become mature eggs FALSE; they will die The production of mature sperm is called ___________________ spermatogenesis Type of reproduction in which offspring are produced by combining the genetic material from 2 parents Sexual reproduction A cell with only one copy of each chromosome is called ___________ Haploid OR 1n A cell which has 2 copies of every chromosome is called _____________ diploid OR 2n Type of division that makes daughter cells which are different from the parent cell and different from each other meiosis The production of a mature egg is called ____________________ oogenesis Phase in which INDEPENDENT ASSORTMENT happens Anaphase I Name 2 ways the DNA in cells gets recombined in new ways during meiosis Crossing over OR independent assortment Phase during which SYNAPSIS happens Prophase I Spermatogenesis produces ____ 4 mature sperm cells Phase in which CROSSING OVER happens Prophase I How many mature eggs are produced during oogenesis? Only 1; the other 3 are polar bodies Tell one phase that is different in meiosis than in mitosis Prophase I- Synapsis & crossing over Anaphase I- independent assortment Metaphase I- pairs line up together Interphase II- No DNA is copied
