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 ...

This is a preview. Log in through your library . Abstract The role of polyploidy in gymnosperms has been evaluated. Polyploidy is found in the progeny of diploid species, in stray trees of otherwise ...

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 ...

For animals, an extra chromosome can result in major problems, but plants are another matter. Many plants can survive an extra copy of their entire genome (polyploidy), and this process often results ...

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