Bulbs are known as perennating organs. They allow plants to survive in adverse conditions and then to grow quickly when the time is right. The swollen rhizomes of irises have a similar function, but asexual reproduction does not rely solely on perennating organs. ...

The flowers of many Habenaria species are often characterised by long spurs and are mostly ...
The cell pinches in half, and now there are two cells of the same organism. Bacteria, yeast, archaebacteria all "practice" asexual reproduction. Even some plants and animals utilize this method to pass on their genes when the conditions are right. Some bacteria can share parts of their DNA...

The evolution and maintenance of sexual reproduction is believed to involve important tradeoffs. Queens of social insects face a dilemma over the costs and benefits of sexual and asexual reproduction. Asexual reproduction by a queen doubles her contribution to the gene pool. However, overuse of asexu...
The balance between sexual and asexual propagation in the establishment of natural stands of Populus nigra was assessed from the genotypes of trees sampled in different natural stands. One site was completely sampled and genotyping proceeded using STS and RAPD markers. Among 118 trees, only four wer...
