Practice question · True or false
In seahorses, where the male carries the developing eggs and invests more per offspring, parental investment theory predicts the MALE will be the choosier sex.
Hints
- Choosiness follows INVESTMENT, not sex.
- Here the male invests more, so the theory points to him being selective.
Show the answer
True
Why
True. Parental investment, not sex, predicts choosiness - so where males invest more (seahorses, jacanas), males become the choosier sex. Assuming females are always the choosier sex is the named pitfall.
