  9. List the steps of meiosis in order

  10. Prophase • Metaphase • Anaphase • Telophase • Cytokinesis • (this then repeats)

  11. During which stage of meiosis does crossing over occur?

  12. Prophase 1

  13. How many cells are produced by the end of cytokinesis 2?

  14. 4

  15. Homologous chromosomes are separated during this stage of meiosis

  16. Anaphase 1

  17. Sister chromatids are separated during this phase of meiosis.

  18. Anaphase 2

  19. After replication, these segments of DNA look like the letter X

  20. chromosome

  21. Somatic cells are 2N, which indicates two sets of chromosomes. What word means 2n?

  22. diploid

  23. Gametes are labeled N because they have one set of chromosomes. What word means N?

  24. Haploid

  25. The left and right side of a chromosome when it looks like an X are called ______

  26. Sister chromatids

  27. The fusion of two gametes creates a diploid cell called a ______

  28. zygote

  29. The chance that a gamete will have the paternal homologue of a chromosome is _____%

  30. 50

  31. The chance that a gamete will have two paternal homologues is ___% (show your calculations)

  32. ½ x ½ = ¼ ¼ = 25%

  33. Set up and evaluate an expression to calculate the probability of a gamete having 5 paternal homologues

  34. ½ x ½ x ½ x ½ x ½ 1/32

  35. Draw all possible gametes that can be produced from the parent cell below X X X X Note: this parent cell has already undergone DNA replication

  36. What is the probability of an Rh+/Rh- man producing a sperm cell with a Y chromosome and an Rh+ gene?

  37. 1/8

  38. Fertilization occurs when a sperm cell and an ovum combine to form one cell. Sperm and ova are both _____.

  39. gametes

  40. The name of the cell created by the fusion of a sperm cell and an ovum is a ______.

  41. zygote

  42. Daily Double!

  43. Not all of the cells created by females during meiosis are used during fertilization. What are these cells that are discarded and how many are made from one cell undergoing meiosis?

  44. Polar bodies

  45. After fertilization occurs, the zygote grows by creating more cells. What process produces these new cells?

  46. meiosis

  47. By mistake, an ovum has two copies of the 21st chromosome. How many copies of the 21st chromosome will the zygote have if the ovum is fertilized by a normal sperm?
