Polyploidy, the condition of possessing more than two complete genomes in a cell, has intrigued biologists for almost a century. Polyploidy is found in many plants and some animal species and today we ...

A detailed phylogenetic study now shows that there is a compelling association between polyploidy and domestication, and that polyploidy more frequently occurs before domestication. However, in a few ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

Polyploidy is a state where a cell contains more copies of the genetic material than the usual "diploid" cell, which contains two copies. Polyploidy often occurs in human diseases and cancers, and its ...

Leading expert on plant evolution and speciation and professor of Iowa State University, Jonathan Wendel, presented his research Thursday on cotton genomes and polyploidy in his presentation “Genes, ...

An unassuming starfish species found around the world has a shocking amount of DNA hidden inside its cells. The brooding brittle star (Amphipholis squamata), which has a tiny disk-shaped body and long ...

Vol. 303, No. 8, Special Issue: Polyploidy in Deep and Shallow Evolutionary Times (October 2017), pp. 1093-1108 (16 pages) Polyploidy is one of the most important evolutionary processes in plants. In ...

Biologists may have pinpointed for the first time the mechanism responsible for cell polyploidy, a state in which cells contain more than two paired sets of chromosomes. An international team of ...

Recent studies have elucidated the ancient polyploid history of the Arabidopsis thaliana (Brassicaceae) genome. The studies concur that there was at least one polyploidy event occurring some 14.5 to ...

Evolution is the basis of biological diversity, driven by mechanisms that allow organisms to adapt and survive. One such ...
