  1. 3. These makes bones and muscles, change eye and hair color, and fight disease. Cells are like factories for building them
  2. 4. DeoxyRiboNucleic Acid
  3. 6. These determine our traits
  4. 9. When everyone's genes are different. Helps protect against disease
  5. 10. eye color, hair color, right-handedness. __________ like these are determined by our genes
  6. 12. What determines which allele is PASSED DOWN to the child
  7. 15. Different versions of the same gene
  8. 17. The two-letter genetic code for a trait. NOT an Italian guy...

  1. 1. These types of genes are always covered up by dominant ones
  2. 2. B = Brown, b = blue What color eyes does this person have: bb
  3. 5. The part of the cell where your DNA and genes are located
  4. 7. In this type of reproduction, TWO parents create a genetically unique offspring
  5. 8. Genetic diversity protects us from being wiped out from ___________
  6. 10. How many alleles do you have for every single gene? (Hint: mom and dad)
  7. 11. The smallest unit of all life
  8. 13. These types of genes always cover up recessive ones
