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 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_______________ 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 Type of cell division shown mitosis Tell one reason why a cell would do this Grow organism bigger Repair injuries Replace worn out cells Producing offspring without using sperm or eggs in which the DNA comes from only 1 parent Asexual reproduction 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 Haploid OR 1n chromosome is called ___________ 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 Phase in which INDEPENDENT ASSORTMENT happens Metaphase 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 Phase in which CROSSING OVER happens Prophase I Tell one phase that is different in meiosis than in mitosis Prophase I- Homologouse chromosomes pair up & crossing over occurs Anaphase I- independent assortment Metaphase I- pairs line up together
