  1. 1. the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
  2. 6. traits that promote an organism's success in a particular environment.
  3. 7. a trait that is expressed only when genotype is homozygous
  4. 10. the deliberate modification of the characteristics of an organism by manipulating its genetic material.
  5. 12. the traits or characteristics that are transferred from parents to the offspring, genetically.
  6. 15. a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
  7. 16. a table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are given.
  8. 19. the practice of mating individuals with desired traits as a means of increasing the frequency of those traits in a population.
  9. 20. A term that describes having two identical versions of the same gene

  1. 2. the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.
  2. 3. a different or distinct form or version of something.
  3. 4. a process of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
  4. 5. A molecule made up of amino acids
  5. 8. the process by which humans choose individual organisms with certain phenotypic trait values for breeding.
  6. 9. the recorded ancestry, especially upper-class ancestry, of a person or family.
  7. 11. the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
  8. 13. A term that describes having two different versions of the same gene
  9. 14. a genetically determined characteristic.
  10. 17. the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
  11. 18. the stock of different genes in an interbreeding population.
