  • Biology courtship
    • physical/chemical differences help species differentiate between their own members and other species
      • helps ensure same species mate.
    • Why necessary?
      • successful courtship helps lead to offspring with maximum chance of survival by:
        • recognising members of own species
          • mating only occurs between same species so fertile offspring
        • Identify mate capable of reproducing
          • Shows sexual maturity both can breed.
        • Form pair bond
          • Pair helps lead to successful mating and raising.
        • Synchronise mating
          • so it takes place when max probability of sperm and egg fusing
    • differences in c. sequences can show biological relations between species/members
