Across
  1. 2. Different forms of a gene
  2. 3. 1 set of chromosomes (half the "normal" number) GAMETES
  3. 6. series of events that cells go through as they grow and divide
  4. 7. 3rd phase of mitosis; chromosomes move APART
  5. 12. 2nd phase of mitosis; chromosomes in the MIDDLE
  6. 13. 1st stage of mitosis - Chromosomes become visable, nuclear envelope dissolves, spindle forms
  7. 14. A sequence of DNA that determines a trait and is passed from parent to offspring
  8. 16. A change in a gene or chromosome.
  9. 17. Cell's division (PMAT) of the nucleus. Final product is 2 cells that are exactly like the parent cell.
  10. 18. 2 different alleles
  11. 20. An allele that is masked when a dominant allele is present
  12. 21. An organism's genetic makeup
  13. 22. genetic code
  14. 23. Cell division that produces reproductive cells in sexually reproducing organisms
Down
  1. 1. 2 sets of chromosomes - the normal number - SOMATIC/BODY CELLS
  2. 4. An organism's physical appearance, or visible traits.
  3. 5. 4th phase of mitosis; TWO new nuclei
  4. 8. The process in reproduction and growth by which a cell divides to form daughter cells
  5. 9. An allele whose trait always shows up in the organism when the allele is present.
  6. 10. Passing of traits from parents to offspring
  7. 11. Scientific study of heredity
  8. 15. An organism that has two identical alleles for a trait
  9. 19. A specific characteristic that varies from one individual to another
