Asexual reproduction. Asexual reproduction in liverworts: a caducous phylloid germinating. Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from either unicellular or multicellular organisms inherit the full set of ...
Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. There are two forms of reproduction: asexual and sexual . In asexual reproduction, an organism can reproduce without the involvement of another organism.
Asexuality is the lack of sexual attraction to others, or low or absent interest in or desire for sexual activity. [ 1][ 2][ 3] It may be considered a sexual orientation or the lack thereof. [ 4][ 5][ 6] It may also be categorized more widely, to include a broad spectrum of asexual sub-identities. [ 7][ 8]
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in ...
Asexual people who desire romantic partnership may have certain gender preferences for their partners, such as hetero romantic, homo romantic, bi romantic or pan romantic.
A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are produced by the same mechanism as in parthenogenesis, but with the requirement that the egg merely be stimulated by the presence of sperm in order to develop. However, the sperm cell does not contribute any genetic material to the offspring.
Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Fragmentation in multicellular or colonial organisms is a form of asexual reproduction or cloning, where an organism is split into fragments upon maturation and the spilted part becomes the new individual. The organism may develop specific organs or zones to shed or be easily broken off. If the splitting occurs without the prior preparation of ...
