Most vertebrates have two sets of chromosomes, one from their mother and one from their father - including humans who are thus diploid. In contrast, polyploidy, meaning to possess three or more sets ...

A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer. Whole genome duplication (WGD) ...

Polyploidy, or whole-genome duplication (WGD), is a major mechanism of genome evolution across the tree of life and is particularly prevalent in plants, where it facilitates the evolution of new ...

A review of work on the origin and phylogenetic relationships of six systems of allopolyploid homosporous ferns and their progenitors serves as the basis for assessing the history and status of ideas ...
