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 ...

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 ...

Polyploidy is a state where a cell contains more copies of the genetic material than the usual "diploid" cell, which contains ...

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 ...

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 ...
