  1. 3. Reproductive cells that contain half the DNA for an organism. These cells can fuse together to form a new organism.
  2. 4. A structure that contains a single molecule of DNA wrapped around proteins and found in the nucleus of eukaryotes.
  3. 6. A permanent change in the DNA base sequence that causes changes in the proteins made. These changes can either be harmful or helpful to the organism.
  4. 9. An allele that blocks another allele.
  5. 10. A section of DNA that has information about a specific trait of an organism.
  6. 11. Female reproductive cell produced in the ovaries.
  7. 12. Large molecules made of amino acids that are required for structure, function, and regulation of tissues and organs.
  8. 15. Asexual reproduction that occurs when a bud forms on a parent organism and then breaks off once the cell is developed forming a new organism.
  9. 18. An allele that is hidden by a dominant allele.
  10. 20. Two alleles for a gene that have different information such as blond hair and brown hair.
  11. 22. Male reproductive cell produced in the testicles.
  12. 23. The process by which the information in DNA is copied for protein production.

  1. 1. Two alleles for a gene that have the same information.
  2. 2. Asexual reproduction that occurs when a parent organism breaks into pieces and each piece develops into a new organism.
  3. 5. The production of offspring by one organism without the joining of sperm and egg; offspring are genetically identical to the original organism.
  4. 6. Alleles that make up an organism.
  5. 7. Organic compounds that join together in large chains to make proteins.
  6. 8. All forms of a gene with different information about a trait.
  7. 13. Specific characteristics of an organism.
  8. 14. Deoxyribonucleic acid is a complex molecule that contains all of the information necessary to build and maintain an organism and is passed from parent to offspring
  9. 16. The final step by which DNA is coded to make proteins.
  10. 17. A form of reproduction in which the genetic material from two different individuals combine to form a new organism.
  11. 19. Observable traits, such as height, eye color, and blood type.
  12. 21. Asexual reproduction that happens when one cell splits into two identical daughter cells.
