  • In which phase of meiosis to the homologous pairs line up in the middle of the cell?
    Metaphase 1
  • What is the male gamete called?
    Sperm
  • In what phase of meiosis does the nuclear envelope disappear and the chromosomes condense to become more visable?
    Prophase 1
  • What is the benefit of crossing over?
    Genetic variation increases
  • In what phase of mitosis do the spindle fibers pull the chromosomes apart by the centromeres?
    Anaphase
  • At what stage of mitosis do the chromosomes line up in the middle of the cell?
    Metaphase
  • Why is sexual reproduction more beneficial in a changing environment?
    It results in more genetic diversity.
  • True or false: Meiosis produces four genetically different cells and mitosis produces two genetically identical cells.
    true
  • What is the female gamete called?
    Egg
  • State the order of the phases of meiosis.
    Prophase 1, metaphase 1, anaphase 1, telophase 1, prophase 2, metaphase 2, anaphase 2, telophase 2
  • In what phase of mitosis do the nuclei of the new cells start to grow around the divided chromosomes?
    Telophase
  • Does the following statement describe mitosis or meiosis? The chromosomes separate and the nucleus divides to create two new genetically identical daughter cells.
    Mitosis
  • In what phase of meiosis do the spindle fibers pull the chromosomes apart, separating them into halves?
    Anaphase 2
  • A single celled protist undergoes reproduction resulting in two identical cells. Is this an example of sexual reproduction or asexual reproduction?
    Asexual
  • Is sexual or asexual reproduction more beneficial in a changing environment?
    Sexual
  • In what phase of meiosis do the spindle fibers pull the homologous pairs apart?
    Anaphase 1
  • In what phase does the cell rest, grow, and replicate its DNA?
    Interphase
  • Are human skin cells haploid or diploid?
    Diploid
  • State the order of the phases of mitosis.
    Prophase, metaphase, anaphase, telophase
  • Are gametes haploid or diploid?
    Haploid
  • What is the process that splits the cytoplasm into two different cells?
    Cytokinesis
