Most living plant and animal species have a certain, relatively small, amount of variation in their genetic make-up. Differences in height, skin and eye color of humans, for example, are very noticeable, but are actually the consequences of very small variations in genetic makeup.

Researchers at Iowa State University, China Agricultural University and the Beijing Genomics Institute in China recently re-sequenced and compared six elite inbred corn lines, including the parents of the most productive commercial hybrids in China.

When comparing the different inbred corn lines, researchers expected to see more variations in the genes than in humans. Surprisingly, researchers found entire genes that were missing from one line to another.
