  1. 4. meiosis in males which produces sperm.
  2. 5. a type of cell division that produces exact copies of the parent cell (2n). Occurs after a zygote forms.
  3. 10. I, phase in which synapsis and crossing over occur.
  4. 12. a 2n=28 individual undergoes meiosis. How many chromosomes will each daughter cell have after meiosis II?
  5. 13. chromosomes that have the same shape and size; "look alike chromosomes".
  6. 14. a type of cell division that reduces the chromosomal number in half to produce gametes.
Down
  1. 1. a brief period of time that occurs between meiosis I and meiosis II.
  2. 2. meiosis in females which produces eggs.
  3. 3. the organ in males that produces gametes.
  4. 5. I, homologue pairs align at the equator during this phase.
  5. 6. a pair of homologues
  6. 7. chromosomal state of zygote, parent cells, and individuals.
  7. 8. process by which homologues pair up; "snap" together.
  8. 9. the first cell formed after fertilization.
  9. 11. chromosomal state of gametes such as egg and sperm.
