- There is formation and fusion of male and female gametes.Â
- Both male and female parents are required. (Hermaphrodites have both male and female gonads in a single body; hence a single parent can also take part in sexual reproduction.)
- The offspring produced will contain half genetic materials (DNA) from the mother, and the other half from the father. Hence, offspring are genetically different from their parents, and each other.
- Crossing over occurs during gametogenesis, and the offspring contain DNA from both parents. This leads to variation and in long term, the evolutionary change leads to the evolution of new species.Â
- The generation time is usually long, with a very long gestation period in higher animals and plants.Â
- There need to be gametogenesis, fertilization, and the development of the zygote and embryo. Hence, there is a huge expense of cellular energy.Â
- Offspring mature slowly so the population growth rate is comparatively slower.
- It is mainly seen in multicellular organisms, especially in higher plants and animals. Humans reproduce by this process only.Â
- Environmental factors have a comparatively lower influence than in asexual reproduction. Â
