#### Abstract

If *x* and *y* belong to a metric space *X *, we call (x,y) a DC1 scrambled pair for f:X→X if the following conditions hold:

If D⊂X is an uncountable set such that every x,y∈D form a DC1 scrambled pair for*f*, we say *f* exhibits *distributional chaos of type 1. * If there exists t>0 such that condition 2) holds for any distinct points x,y∈D, then the chaos is said to be *uniform*. A *dendrite* is a locally connected, uniquely arcwise connected, compact metric space. In this paper we show that a certain family of quadratic Julia sets (one that contains all the quadratic Julia sets which are dendrites and many others which contain circles) has uniform DC1 chaos.
