• Title Fornicating Fruit Flies
• Introduction Today, you and a partner will
  generate and observe fruit fly offspring (babies)
  by mating a male and female fruit fly (species
  name Drosophila melanogaster). Fruit flies are
  commonly used in genetics, the study of genes and
  patterns of inheritance. Inheritance is the
  passing of genes and traits from parent to
  offspring.
• Organisms reproduce or produce new offspring
  using one of two methods sexual or asexual
  reproduction. Most animals, like humans and
  fruit flies, generate offspring by sexual
  reproduction. The offspring from sexual
  reproduction inherit genetic information from two
  different organisms. In contrast, the offspring
  of asexual reproduction only inherit genetic
  information from one parent. Some organisms are
  able to do both!
