Budding is relative new method of reproduction. In this a small growth occurs on parent body which develops into new individual. Sexual Reproduction started from protists. In this there is formation of gamete. Along with this meiosis occurs which reduces the chromosome number. It leads to formation of zygote along with fusion of gametes referred as Fertilization. Syngamy and Conjugation are two methods of sexual reproduction. In syngamy there is permanent fusion of gametes to produce a zygote. It can be iso, aniso and oogamy.
The evolution of sexual reproduction describes how sexually reproducing animals, plants, fungi and protists evolved from a common ancestor that was a single celled eukaryotic species. There are a few species which have secondarily lost the ability to reproduce sexually, such as Bdelloidea and some parthenocarpic plants.any protists reproduce sexually, as do the multicellular plants, animals, and fungi. In the eukaryotic fossil record, sexual reproduction first appeared by 1.2 billion years ago in the Proterozoic Eon. All sexually reproducing eukaryotic organisms derive from a single-celled common ancestor.
