Gene duplication

... force since the emergence of the universal common ancestor . Major genome duplication events are not uncommon. It is predicted that the entire yeast genome underwent duplication only ~1,000,000 years ago. Plants are the most prolific genome duplicators. Wheat for example is hexaploid (a specific ...
