Polyploidy is generally thought to be a main driving force of speciation, as the polyploids possess advantages in genome buffering, heterosis fixing, and plasticity evolving. From the perspective of ...

Heterostyly, a floral polymorphism where a species produces two or three distinct flower types with reciprocal arrangements of stigmas and anthers, boosts pollination accuracy, reduces sexual ...

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 ...

One of the biggest challenges in cancer research is understanding why some tumor cells become especially aggressive, invasive and resistant to treatment. Scientists have increasingly linked these ...

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 ...

Researchers at Tulane University School of Medicine have discovered that if animal cells gain an extra set of chromosomes, a condition known as polyploidy, they activate a stress signaling pathway ...

For decades, scientists have struggled to untangle the genetic complexity of crops with multiple chromosome sets. Now, researchers have unveiled a cost-effective sequencing method, dpMIG-seq, that ...

Polyploid plants carry multiple ancestral genomes within a single nucleus, a condition that can boost adaptability but also trigger internal genetic conflict. How these distinct genomes avoid ...

Scientists have long known that some cells in a given tissue undergo a process of duplicating their entire genome without dividing – a process called endopolyploidy, where cellular ploidy is the copy ...
