- **Parthenogenesis**: This is a form of asexual reproduction where an organism develops from an unfertilized egg. Examples include certain species of honeybees and some plants like bananas.
- **Apomixis**: This refers to a form of asexual reproduction that occurs in plants where seeds are produced without fertilization, but it is not the same as the broader concept of development from an unfertilized egg.
