Developmental noise or stochastic noise is a concept within developmental biology in which the observable characteristics or traits (phenotype) varies between individuals even though both individuals share the same genetic code (genotypes) and the other environmental factors are completely the same.[1][2] Factors that influence the effect include stochastic, or randomized, gene expression and other cellular noise.[3]
