Across
  1. 3. Shape of DNA
  2. 10. the passing of traits from parents to offspring
  3. 11. the study of how traits are passed from parent to offspring
  4. 12. Chemical base that always pairs with Adenine
  5. 13. a diagram used to show the inheritance of traits over generations of a family
  6. 15. allele that blocks or "covers up" the weaker alleles; when present it will always show in the phenotype; represented by an upper-case letter
Down
  1. 1. a tool used to predict the genetic outcomes of a cross between parents' traits
  2. 2. What does DNA stand for?
  3. 4. possesses the same alleles; Example: RR, rr
  4. 5. Chemical Base that always pairs with Guanine
  5. 6. different forms of a gene
  6. 7. allele that is weaker and is "hidden/covered up" by the stronger allele: represented by a lower-case letter
  7. 8. a characteristic of an organism that is passed down from parents to offspring.; Can be determined by genes, the environment, or a combination of both.
  8. 9. combination of different alleles; Example: Rr
  9. 13. the physical appearance of an organism; based on the genotype
  10. 14. genetic make-up of an organism; determines the phenotype
