Some cons of sexual reproduction are:
1. It depends on pairing between two adults and slows how quickly new offspring can be produced.
2. It uses extra energy during mate search and reduces what organisms can keep for staying alive.
3. It requires a longer reproductive process and reduces how many young can be formed at once.
4. It requires partners to locate each other and raises the likelihood that reproduction does not happen.
5. It forces individuals to move openly while seeking partners and increases the chances of predators spotting them.
