Sexual reproduction is one type of reproduction in which gametes from parents are produced by meiosis so are haploid. A male individual produces sperms, and females produce egg cells. Both sperm and egg unite to form a zygote that develops into a diploid organism.

Asexual reproduction is a mode of reproduction that involves only a single parent and produces genetically identical offspring. In this type of reproduction, gametes are not produced and fused as in sexual reproduction.

In plants, vegetative propagation is the form of asexual reproduction that produces a complete plant from any part of the plant containing adventitious buds such as root, stolon, and offset.

Self-fertilization is considered sexual reproduction because it involves the fusion of gametes during fertilization.

So, the offspring is genetically different from the parents. Here, parents are considered gametophytes produced from the plants. Gametes produced by the same plant or flower have different genotypes, and when they unite, different genotypes are produced.
