Chapter 13 Meiosis and Sexual Life Cycles Review
  1. In reproduction, one parent produces genetically identical offspring by fission or by .
     
     
     
     
  2. In reproduction, two parents produce offspring that have unique combinations of inherited from each parent.
     
     
     
     
  3. Genes are located on chromosomes, which can be visualized under the light microscope to create a .
     
     
     
     
  4. are sex cells that are produced in organs called by meiosis.
     
     
     
     
    Asexual and Sexual Life Cycles and Meiosis Overview:
     
     
     
     
  5. Since meiosis reduces the number of chromosome sets from to , two cellular divisions are required, preceded by a single .
     
     
     
     
    • Meiosis I is the chromosome division.
       
       
       
       
    • Meiosis II then produces haploid daughter cells.
