(i) Parthenocarpic fruits are formed when ovary develops into fruit without fertilisation. Apomictic seeds are formed when formation of seeds take place without fertilisation.

(ii) To maintain hybrid characters (year after year in a desired plant) and to avoid buying hybrid seeds every year (expensive seeds) farmers prefer using apomictic seeds.

Yes. These seeds are formed without fertilisation hence there is no genetic variation .This feature is helpful to preserve the desirable characters for many years.

Seeds that are produced without fertilisation are referred to as apomictic. 

Advantage: Desired characters are retained in offspring (progeny) as there is no segregation of characters in offspring (progeny). Seed production is assured even in absence of pollinators. Apomictic seeds are economical as they can be used to grow crops year after year. 

Disadvantage: Cannot control accumulation of deleterious genetic mutation. These are usually restricted to narrow ecological niches and lack ability to adapt to changing environment.

Dormancy of mature seeds are important for storage of seeds which can be used as food throughout the year and also to raise crop in the next season.
