sexual and asexual reproduction

In bacterial sexual reproduction there is no meiosis, formation of gametes and zygote. Instead, it involves transfer of a portion of genetic material (DNA) from a donor cell to a recipient cell. This process is called as genetic recombination or parasexuality . It is known to oc..

Sexual reproduction is known to occur in all groups of fungi except the Fungi imperfecti or Dueteromycetes . It may involve fusion of gametes, gametangia or hyphae. The process may involve only fusion of cytoplasm ( plasmogamy ) or fusion of nuclei ( karyogamy ) or production of..

In flowering plants, flowers have taken the place of conventional sex organs, and the ovules which later on develop into seeds are enclosed within an ovary. The sexual reproduction in angiosperms involves the fusion of two gametes, the male and the female. The male gametes are p..

Definition - Production of offsprings by a single parent without the formation of gametes is called asexual reproduction. It is also called as somatogenic reproduction..

Advantages of Asexual Reproduction - There is no need for sexual partners. It is a very rapid proces..

Types of Asexual Reproduction - The principal forms of asexual reproduction are Binary fission Multiple fission Budding Fragmentati..

Regeneration of new plants from the vegetative parts of the parent plant is called vegetative propagation or vegetative reproduction. Vegetative propagation is done with the help of vegetative parts such as roots, stem or leaves. These parts may also be variously modified for vegeta..
