Across
  1. 4. Genotype with two identical forms of an allele; AA or aa
  2. 8. Any change in DNA
  3. 9. Second most specific level of classification; comes first in binomial nomenclature
  4. 12. Pairs with Adenine (A) in RNA
  5. 14. Process in which mRNA is read by a ribosome to make a protein
  6. 17. Type of inheritance where two dominant traits both show up fully
  7. 21. Domain that contains all prokaryote that live in extreme environments
  8. 22. Process in which a new copy of DNA is made from original DNA
  9. 24. ______ nomenclature; type of scientific naming that uses two Latin names
  10. 26. DNA is changed by removing a single base
  11. 27. Type of inheritance where two dominant traits mix
  12. 28. Type of inheritance where a gene is passed to offspring on the X or Y chromosome
  13. 29. Idea that organisms fit for their environment survive, breed and pass on good traits
  14. 30. English biology who thought successful individuals would breed and pass on good traits
Down
  1. 1. Three copies of a single chromosome
  2. 2. Organism or group of organisms on a cladogram that share no traits; usually farthest to left
  3. 3. V-shaped diagram used to show evolutionary relationships between organisms
  4. 5. DNA is changed by replacing a single base with another base
  5. 6. Most specific level of classification; comes second in binomial nomenclature
  6. 7. Domain that contains the majority of prokaryote cells
  7. 10. French biologist who thought organisms changed their body structures
  8. 11. Adjective given to replication, because each new DNA is one old strand, one new strand
  9. 13. Structures that no longer serve their original purpose for an organism (human tailbone)
  10. 15. DNA is changed by adding a single base
  11. 16. Structures with similar function, but not made of the same tissues (bird wing vs butterfly wing)
  12. 18. Domain that contains all cells with a nucleus
  13. 19. Genotype with two different forms of an allele; Aa
  14. 20. Pairs with Adenine (A) in DNA
  15. 23. Structures with similar functions and made of similar tissues (bird wing vs bat wing)
  16. 25. Process in which mRNA is made from DNA
