Answer:

This isolating mechanism is Prezygotic and behavioral.

Option: (A)

Explanation:

  • Drosophila is a genus of flies which is called 'vinegar flies' or 'small fruit flies' or 'wine flies'.
  • Reproductive isolation means that different species might live together, but their own properties prevent them from 'interbreeding'.
  • Preventing the "fertilization of eggs" is called prezygotic isolation.
  • Temporal isolation, behavioral isolation, habitat isolation, gametic isolation, mechanical isolation are prezygotic isolating mechanism.
  • Behavioral isolation refers when two populations belonging to same species will develop some kind of differences in behavior, typically in 'mating rituals'.
