Across
  1. 3. A display of the chromosome pairs of a cell arranged by size and shape.
  2. 5. Normal diploid body cell
  3. 6. 2 sets of chromosomes
  4. 7. 2nd phase of mitosis, during which the chromosomes line up across the center of the cell
  5. 10. Cell division that produces reproductive cells in sexually reproducing organisms
  6. 11. 4th stage of mitosis- nuclear membrane reforms, chromosomes decondense, and centrioles disappear.
  7. 12. division of the cytoplasm
  8. 14. disorder in which some of the body's cells lose the ability to control growth.
  9. 18. A reproductive process that involves two parents that combine their genetic material to produce a new organism
  10. 19. having a single set of unpaired chromosomes
  11. 20. Identical copies of a chromosome; full sets of these are created during the S subphase of interphase.
Down
  1. 1. 1st stage of mitosis - chromosomes condense, nuclear membrane breaks down, and centrioles appear.
  2. 2. cell division in which the nucleus divides into nuclei containing the same number of chromosomes
  3. 4. separates sister chromatids
  4. 8. series of events that cells go through as they grow and divide
  5. 9. Process by which a single parent reproduces by itself
  6. 13. the 3rd phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
  7. 15. a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum.
  8. 16. specialized cell involved in sexual reproduction
  9. 17. separates homologous chromosomes
