  3. 7. base substitutions, insertions, and deletions.
  4. 9. Traits with 2+ genes that control 1 phenotype.
  5. 11. Traits with more than 2 possible alleles.
  6. 13. matching allels
  7. 14. each chromosome separated independently.

Down
  1. 1. Parts added, deleted, moved, and inverted.
  2. 2. Alleles(variations of a trait) may be dominant(always expressed in phenotype) or recessive(not always expressed).

  6. 8. Occur in noncoding DNA.
  7. 10. Father of genetics, first to study and systematically explain inheritance of traits, studied single gene inheritance in pea plants, described simple dominance.
  8. 12. When no alleles are dominant the heterozygous offspring will not display either parental phenotypes.
