Snapdragons are tall plants, and flower in a range of colors. In Spain, where snapdragons grow wild, these flower colors show a remarkable pattern: areas of magenta and yellow blooming flowers are separated by just a two kilometer long stretch in which flower colors mix. Scientists have investigated the causes of this pattern and identified the genes responsible for flower color difference from DNA sequence data.
