    • What does the term 'heredity' mean?

  • The process by which characteristics are passed from parents to offspring (correct)
  • The process by which dominant traits are inherited
  • The process by which characteristics are influenced by the environment
  • The process by which genetic variations occur

    • What does the term 'dominant trait' mean?

  • A trait that is expressed when an individual has two identical alleles for that trait
