The study of complex dynamics is currently of great interest in mathematics and related scientific fields. Invariant laminations, invented by William Thurston, are abstract mathematical structures which represent the dynamics of complex polynomials but are easier to understand. We will define a sibling portrait of an invariant lamination which can be thought of as a “snap shot” of the dynamical system. We will show the existence of a one-to-one correspondence between sibling portraits and bicolored trees, mathematical objects from graph theory. This immediately provides a count for the number of different sibling portraits possible.
