||Primary source abstract: "Using probabilistic modeling, [investigators] defined the sources of error in SOP [sensory organ precursor] selection and examined how they depend on the underlying molecular circuit."
||P.1 middle column bottom paragraph: "Large bristles on the adult fly develop from a sensory organ precursor (SOP) cell chosen from a prepatterned cluster. The mechanism functions with a low error rate. Barad and colleagues observed bristle duplication with a frequency of approximately 1% in a specific set of bristles, whereas loss of bristles, if it occurs at all, is less frequent (primary source)."
