  • What do we call cells that contain half the genetic material?
    Haploid cells
  • What happens when two gametes combine?
    They form a normal diploid cell
  • What is the term for cells with two sets of genetic information?
    Diploid cells
  • What is the first step in meiosis?

  • What happens during the second division of meiosis?
    Chromosome arms are pulled apart
  • How many cells are produced at the end of meiosis?
    Four cells
  • Why are gametes genetically unique?
    Due to tiny changes during meiosis
