Some asexual lineages have also developed novel mechanisms to substitute sex and mimic its evolutionary advantages.doi:10.1016/B978-0-12-809633-8.20529-3I. SchnK. MartensEncyclopedia of Reproduction (Second Edition)
Sexual reproduction includes the involvement of two parents. Organisms that reproduce by sexual means are known as sexual organisms. These organisms require a mate to reproduce, and the mate should belong to the same species to which the organism belongs. Many plants and animals can reproduce ...
Our findings indicate that Hox genes regulate asexual reproduction via the emergence and modulation of A/P segmentation and behavior in adult animals. We previously identified requirements for the Wnt signaling genesβ-catenin, apc, dshB, andwnt11-6as well as the TGF-β signaling genesactR-1ands...
Asexual reproduction is a feature of lower animals and occurs in all groups of plants, including ANGIOSPERMS, usually in addition to sexual reproduction. Perhaps the fixed location of many plants makes this type of reproduction particularly suitable. Also occurs in MICROORGANISMS. There are several ...
The different types of asexual reproduction are binary fission, budding, vegetative propagation, spore formation (sporogenesis), fragmentation, parthenogenesis, and apomixis. The organisms that reproduce through asexual means are bacteria, archaea, many plants, fungi, and certain animals....
Since this fragment has the same DNA as the parent, in fragmentation asexual reproduction the offspring will be a clone of the parent. This astoundingly simple method of reproduction can be performed by many plants and several unique species of animals. ...
Bacteria, fungi, protists, plants, and archaea have all been known to use asexual reproduction to reproduce. Among animals, it is relatively rare, however. There are a number of theories to explain this, with many focusing on the increased diversity available through sexual reproduction. When an...
