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

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 ...

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 ...

The figure shows the possible paths that result in the sudden transition from diploidy to polyploidy and the gradual transition from polyploidy to diploidy. The hybridization events that result in ...

A new editorial was published in Volume 18 of Aging-US on February 8, 2026, titled "Polyploidy-induced senescence: Linking development, differentiation, repair, and (possibly) cancer?" In this ...

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.

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, ...

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 ...

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 ...

The predominance of sexual reproduction despite its costs indicates that sex provides substantial benefits, which are usually thought to derive from the direct genetic consequences of recombination ...

REISMAN, Zuelzer and Mitani 1 described polyploidy and endoreduplication of chromosomes in a patient being treated for acute leukemia. They ascribed these abnormalities to a primary chromosomal ...
