title: Flipping coins in the fly retina.
abstract: Color vision in Drosophila melanogaster relies on the presence of two different subtypes of ommatidia: the "green" and "blue." These two classes are distributed randomly throughout the retina. The decision of a given ommatidium to take on the "green" or "blue" fate seems to be based on a stochastic mechanism. Here we compare the stochastic choice of photoreceptors in the fly retina with other known examples of random choices in both sensory and other systems.
