  1. 3. dominance when two traits produce a blended phenotype
  2. 6. different forms of genes that result in different traits
  3. 11. squares Mendel used to determine the probability of traits passing to offspring
  4. 12. the process by which organisms with certain adaptations survive to pass on their traits to a greater number of offspring
  5. 15. both traits are present in hybrid offspring, but without blending
