Small variations in genetic code can team up to have big impact

Large sets of variations in the genetic code that do not individually appear to have much effect can collectively produce significant changes in an organism's physical characteristics, scientists have definitively demonstrated. Studying the budding yeast Saccharomyces cerevisiae, researchers found that the effects of these genetic variants can depend on four or more other variants in an individual's genome.
