Analysis of genome rearrangements in molecular biology started in the late s, when Dobzhansky and Sturtevant published a milestone paper presenting a rearrangement scenario with inversions for the species of Drosophila. Analysis of genomes evolving by inversions leads to a combinatorial problem of s

We construct a pinching semiconjugacy from a quadratic polynomial $\fc(z)=z^2+c$ with $c \in (0, 1/4)$ to $\fq(z)=z^2+1/4$ on the sphere. By lifting this semiconjugacy to their natural extensions, we investigate the structure of the regular leaf space of $\fq$ in detail.
