Yes, they are different. Parthenocarpy is the condition in which fruits are developed without fertilization, while apomixis is a condition in which seeds are developed without fertilization. Fertilization is absent in both the case but seeds are present only in apomixis. Parthenocarpic fruits are seedless. Apomixis produces genetically indentified mother cells whereas parthenocarpy produces genetically identified offsprings. Benefits of Parthenocarpy: Seedless fruits are easier to consume; especially those fruits which naturally contain too many seeds, e.g. papaya, watermelon and banana. Benefits of Apomixis: Apomixis can be used to produce apomicts hybrid seeds so that farmers  not need to buy hybrid seeds every year. This will help in drastically cutting the cost for farmers. Apomictic seeds produce clones of the parent plant, so a plant with desired characteristics can be grown apomictically than, through sexual reproduction.
