  2. What is the haploid number for the cell type pictured above? 1
  3. Look at stage 2. a. How many chromosomes are there? 2 b. How many chromosomes came from the mother? 1 c. How many chromosomes came from the father? 1 d. Is the DNA replicated or unreplicated? replicated e. How many chromatids are there? 4
  4. In stage 6, are the cells haploid or diploid? haploid

  6. Between which stages would the sister chromatids separate? stage 4 and 5
  7. Between which stages would the homologous chromosomes separate? stage 2 and 3

Mitosis/Meiosis Test Review Sheet

  1. Normal fruit fly body cells have 4 pairs of chromosomes. What is a diploid number for a fruit fly? 8
  2. If a cell that originally has 16 total chromosomes divides by mitosis, how many chromosomes will be in each daughter cell? 16
  3. If a cell that originally has 16 total chromosomes divides by meiosis, how many chromosomes will be in each daughter cell? 8
  4. List four differences between mitosis and meiosis. Mitosis makes 2 cells; meiosis makes 4 cells. Mitosis makes body cells (somatic cells); meiosis makes sex cells (gametes) Mitosis is for growth and repair; meiosis is for sexual reproduction. Mitosis makes diploid cells; meiosis makes haploid cells. Meiosis has crossing over and mitosis does not.
  5. List three similarities between mitosis and meiosis. They both start as diploid cells. Interphase occurs before both of them. Both are a form of nuclear division.
  6. If this were a body cell, what would the diploid number be? 12
  7. If this were a body cell, what would the haploid number be? 6
  8. How do mitosis and meiosis lead to the formation of a child? Meiosis creates the sex cells in the parents. The sex cells (sperm and egg) combine to form the first cell of the child. This gives the child all of the DNA they need (1 set from egg and 1 set from sperm). That cell then goes through mitosis to create the body of the child.

Mitosis/Meiosis Test Review Sheet

  1. What is the difference between a chromatid and chromosome? A chromatid is an exact copy of another chromosome. One chromosome can be made up of 2 chromatids after replication if they are held together by the centromere or it can be made up of only 1 chromatid after they separate.
  2. What are some factors that regulate cell growth? Cyclins, growth factors, contact with other cells,
  3. What happens if a cell ignores these factors and does not/can not regulate its growth rate? What would this look like? cancer or tumors happen when a cell ignores the cell regulators. It would look like a giant mass of cells growing more than the area it has.
  4. What is the correct order for these pictures? What would the next step look like? What is this cell’s chromosome number? D, A, C, B chromosome number is 4 this is mitosis next step would be two cells each with their own nucleus and set of DNA.
