Abstract
We consider some natural one-parameter unfoldingsf μ, of a unimodal mapf 0 whose periodic points are hyperbolic and whose critical point is nondegenerate and eventually periodic. Among other facts, it follows from our theorems that, if the Julia set off 0 does not contain intervals, the relative measure of the bifurcation set is zero at zero.
