Parthenocarpy is the development of fruit without fertilization, while parthenogenesis is the development of an organism from an unfertilized egg.
Parthenocarpy can occur naturally in some plant species, or it can be induced artificially in others, such as in the production of seedless fruits.
Parthenogenesis, on the other hand, is a form of asexual reproduction where an egg develops into a new organism without fertilization by a sperm. It is found in some invertebrates and lower vertebrates.
