  8. 20. the four reproductive cells produced by meiosis type of cell division necessary for sexual reproduction
  9. 22. used to translate code from the dna
  10. 24. when the chromosomes attached at the center, or centromeres line up on the spindle at the center of the cell
  11. 26. combination of alleles inherited from the parents
  12. 27. a change in a gene, structure, or a combination of genes
  13. 29. the entire collection of alleles of genotypes
  14. 30. reproductive cells in the ovaries
  15. 31. chromatin again forms from the chromosomes and a cell membrane begins to grow across the center between the two nuclei
  16. 33. alternate forms of genes
  17. 34. differentiation cells take on their unique structure as part of the team of the body
  18. 35. inherits two of the same alleles for a particular trait either both dominant or both recessive
  19. 36. when the expression of genes can be turned on or off
Down
  1. 1. used to express the possible combinations for a certain trait an offspring may inherit
  2. 2. when the nucleus of the cell organizes the chromatin material into structures called chromosome
  3. 3. carries dna
  4. 4. cells all cells of the body except for reproductive cells
  5. 6. when both traits appear in the F1 generation and contribute to the phenotype of the offspring
  6. 8. the resting period before meiosis II begins
  7. 9. the passing of traits from a parent to offspring
  8. 10. when one allele is stronger than the other
  9. 11. when one trait is not complete over the other
  10. 12. the processes of mitosis and cytokinesis
  11. 14. genetic basis of life
  12. 16. the weaker gene
  13. 17. genes genes that direct body plan development
  14. 21. reproduction results in offspring that are identical to the single parent cell
  15. 23. involves getting rid of mutated gene, fixing the mutated gene, or replacing the mutated gene
  16. 24. the name for the process of asexual reproduction
  17. 25. study of traits passed from generation to generation
  18. 28. chromosomes separate at the center and the spindle pulls them toward either end of the cell
  19. 29. specific portions of DNA
  20. 32. inherits one dominant allele and one recessive allele
