IndiaA study published in Science Advances explores how wild snapdragons in the Pyrenees use color variation to attract pollinators like bees. Researchers from the John Innes Centre, along with collaborators in Austria, China, and Australia, analyzed how seven genes work together to create precise color patterns in snapdragons. Two varieties of the plant—one with magenta blooms and a yellow center, and another with yellow flowers and a magenta spot—demonstrate how subtle genetic differences influence pollinator attraction. In areas where these varieties interbreed, the resulting hybrids display intermediate colors, but natural selection limits this mixing to a narrow 1 km zone. Scientists use this phenomenon to study how strong natural selection acts on specific genes.
