Asexual reproduction

thumb|upright=1.35|Many organisms, including aspen trees, reproduce by cloning, often creating large groups of organisms with the same [[DNA. One example depicted here is quaking aspen.]]

biological process in which new individuals are produced by either a single cell or a group of cells, in the absence of any sexual process

thumb|upright=1.3|Corbicula leana is one of the species of its genus known to be capable of reproducing androgenetically without females. Androgenesis is a system of asexual reproduction that requires the presence of eggs and occurs when a zygote is produced with only paternal nuclear genes. During standard sexual reproduction, one female parent and one male parent each produce haploid gametes (such as a sperm or egg cell, each containing only a single set of chromosomes), which recombine to create offspring with genetic material from both parents. However, in androgenesis, there is no recombi

The baby plant is an exact clone of the mother plant, sometimes flowering while still attached to the mother. The word is Hawaiian for 'baby' or 'child', literally meaning 'the little one'.

It has the form of a small cushion at the bottom of which short crowded conidiophores are formed. The spores escape through an opening at the top.

thumb|upright=2.0|Honey bees produce [[haploid males from unfertilized eggs]] Arrhenotoky (from Greek ἄρρην árrhēn "male" and τόκος tókos "birth"), also known as arrhenotokous parthenogenesis, is a form of parthenogenesis in which unfertilized eggs develop into males. In most cases, parthenogenesis produces exclusively female offspring, hence the distinction.
