While polyploidy provides genetic redundancy by allowing mutations without affecting survival, it can also slow evolutionary progress by diluting beneficial mutations. This paradox has intrigued ...

This condition, called polyploidy, reduces or eliminates genetic exchange with other yeast strains, therefore maintaining the brewing characteristics of yeast strains. Polyploidy is also found in ...

Assistant Professor of Biology Vicki Losick admits she harbors a desire to change the world a little bit. “I want to make ‘polyploidy’ a household word,” Losick said in her Higgins Hall office, next ...

He concludes that polyploidy has not contributed any lasting genetic redundancy to the yeast genome. Instead, he suggests that whole-genome duplication generated a transient wave of redundancy ...

Plant genetics deals with heredity in plants ... as flowers develop at the end of branches composed of somatic cells; polyploidy is more common; and plants additionally contain chloroplastic ...

A recent study at Earth-Life Science Institute (ELSI) at Institute of Science Tokyo has developed a theoretical model that uncovers the dual role of polyploidy—organisms carrying extra genome ...
