  1. 1. the one that prevents the action of another allele from manifesting itself.
  2. 7. fixed and specific position of a gene on a chromosome
  3. 8. Fragment of DNA that encodes the information necessary for a trait or character
  4. 9. replacement of one base with another
  5. 13. mutation change at only one base pair
  6. 15. Set of genes and genetic information that make up an individual of any species. It is passed from generation to generation
  7. 17. part of a chromosome moves to another chromosome
  8. 19. Mechanisms by which an individual´s traits are transmitted to descendants
  9. 20. it allows x-linked gene expression to be equivalent to individuals with both Xs

  1. 2. Variant in the nucleotide sequence of a gene that determines a particular trait in an individual
  2. 3. The alleles of the gene are the same (they determine the same variant)
  3. 4. mutation insertion/deletion of bases causes shift in reading frame, resulting in different amino acid sequence
  4. 5. loss of one or more nucleotides from a segment of DNA
  5. 6. it only manifests itself in the absence of the dominant allele (purebreds of that characteristic)
  6. 10. The alleles of the gene determine different variants
  7. 11. Expression in physical, observable form of the characteristics of an individual of any species. It may be due to genes, environmental factors or both
  8. 12. one or more copies of a DNA segment or gene are duplicated
  9. 14. alterations in the genetic material of an organism that can lead to changes in the phenotype
  10. 16. addition of one or more nucleotides into a segment of DNA or RNA
  11. 18. a section of a chromosome is reversed, so the orientation of genes on the chromosome is changed
