  2. 7. An organism that is an exact genetic copy of another organism.
  3. 10. A version of a gene that always shows its trait, even if you only have one copy. It overpowers the recessive allele.
  4. 11. The specific combination of alleles you have for a trait. The genetic makeup (like Bb or bb).
  5. 14. A version of a gene that only shows its trait if you have two copies of it. It's like a hidden trait.

  1. 1. How likely something is to happen.
  2. 3. Different versions of a gene. For example, there's an allele for brown eyes and an allele for blue eyes.
  3. 4. Long strands of DNA, like threads, that contain all your genetic information.
  4. 5. The physical expression of a trait. What you actually see (like blue eyes).
  5. 6. A square used to predict the possible combinations of genes offspring can inherit from their parents.
  6. 8. The molecule that carries genetic information.
  7. 9. Having two different versions of a gene for a trait (one from each parent).
  8. 12. Having two identical versions of a gene for a trait (one from each parent).
  9. 13. small sections of DNA on chromosomes that determine specific traits. Think of them as the instructions for building a characteristic.
  10. 15. A characteristic you have, like eye color or height. It can come from your parents or be influenced by your surroundings.
