Solution:
Answer
Sexual reproduction :the production of new living organisms by combining genetic information from two individuals of different types (sexes). Since both individuals have different genetic make up so variation is maximum
Nucellar polyembryony :Zygotic and nucellar embryos can occur in the same seed, and a zygotic embryo can divide to produce multiple embryos. . Thus same genetic material with little variation.
Vegetative reproduction : A form of asexual reproduction in plants, in which multicellular structures become detached from the parent plant and develop into new individuals that are genetically identical to the parent plant.
Parthenogenesis reproduction from an ovum without fertilization
