In your notebook, Name 5 similarities and 5 differences between mitosis and meiosis. http://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter2/animation__comparison_of_meiosis_and_mitosis__quiz_1_.html

Mitosis Meiosis 4 n/a Type of Cell (Gametes or Somatic Cells) Genetically Identical (yes or no) Number of Divisions (1 or 2) Sets of Chromosomes in the beginning 4 Sets of Chromosomes in the end (diploid or haploid) Crossing Over / Recombination Phase n/a Independent Assortment Phase

Key Definitions Gamete: reproductive cells Somatic Cells: body cells Haploid: 1 set of chromosomes Diploid: 2 sets of chromosomes Crossing Over/ Recombination: exchanging parts of two chromosomes Independent Assortment: process where different chromosomes go to different cells
