  2. 6. the physically expressed characteristics or traits of an organism. (Ex: Tall)
  3. 7. Crosses involving TWO genes for TWO traits.
  4. 14. Law that states One trait has NO EFFECT on another trait.
  5. 16. the scientific study of heredity.
  6. 17. Diagram showing the trait probability between all pairs in a family tree.

  1. 1. Crosses involving TWO alleles for ONE trait.
  2. 2. Crosses involving TWO alleles for traits that effect males more.
  3. 3. Crosses involving ONE gene for ONE trait.
  4. 5. when only 1 copy of allele is needed to be expressed (takes over).
  5. 8. passing of traits from parents to offspring.
  6. 9. when an organism has two alleles for the trait that are the SAME.
  7. 10. instructions passed from parents to offspring.
  8. 11. when an organism has two alleles for the trait that are DIFFERENT.
  9. 12. When two copies of the allele are needed to be expressed (disappears).
  10. 13. the allele combination (Ex: TT)
  11. 15. Law that states Alleles of gene separate in Meiosis so you inherit ONE copy from each parent.
