  4. 9. genetic disorders a type of genetic disorder that develop because of a change (mutation) in one or more gene; typically missing or duplicated chromosome material
  5. 11. a threadlike structure found in the nucleus of most living cells, carrying genetic information in the form of genes

  7. 10. blindness a genetic disorder where a person has a reduced ability to distinguish between colors when compared to the standard for normal human color vision; usually affects only males
