Polyploidy, or whole-genome doubling, is one of evolution's most powerful forces in plants, yet its real-world consequences ...

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, ...

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 ...

A Chinese-German team has mapped how snow carps, which recently doubled their genomes, are gradually returning to a stable diploid state. The research shows that rediploidization begins with ...

Plants show a higher variation in chromosome numbers than animals do, mainly because of polyploidy -- the occurrence of more than two sets of chromosomes. In plants, polyploidy can cause reproductive ...

Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a ...

For animals, inheriting more than the usual two copies of DNA is usually a very bad thing. It can happen when two sperm fertilize one egg, or when sexual cell division errs, leaving a sperm or an egg ...

Evolution is the basis of biological diversity, driven by mechanisms that allow organisms to adapt and survive. One such mechanism is polyploidy, where organisms carry extra copies of their genomes.

“Our work highlights the need to study polyploidy and senescence in concert to understand their roles in aging, cancer, and therapeutic resistance.” “Our work highlights the need to study polyploidy ...
