4. 1. Sexes exist as separate male and female 2. Hermaphrodite 3. Parthenogenesis (babies produced from unfertilized eggs)

5.  External  Internal

6.  Single pair matings  Multiple matings of individuals  Polygamy: polygyny, polyandry  promiscuity

7.  The survival of the young depends on both parents.  What for?  Partners for the breeding season, or partners for life?

8.  Polyandry  Polygyny

9.  Harem polygyny 1 dominant male (bird) in a group of females.  Serial polygyny 1 male attracts passing females. Lekking

11.  Female is often larger and more brightly coloured.  Male is in charge of the incubation, the female moves on.

14.  Oviparity Eggs are released and embryos develop outside the body.  Viviparity Embryos develop within the mother’s body and are born as miniature copies of the adult.

15.  Reptile and bird eggs  Fish eggs
