More genes are active in high-performance corn

When two maize inbred lines are crossed with each other, an interesting effect occurs: The hybrid offspring have a significantly higher yield than either of the two parent plants. Scientists at the University of Bonn have now investigated a number of genetically distinct hybrids. They showed that the offspring had many more active genes than the original parents. These results may help in the cultivation of even higher-yielding maize varieties. They are published in the journalĀ Current Biology.
