May 9, 2018 at 16:33 | comment | added | Jason Starr | I assume that you are excluding constant morphisms. You can produce a dominant morphism as the composition of any dominant, finite morphism $q:C\to \mathbb{P}^1$ from a smooth curve $C$ of genus $g$ and the normalization $\nu:\mathbb{P}^1\to B$ of an irreducible curve $B$ of arithmetic genus $g$ and geometric genus $0$, e.g., a curve with $g$ nodes. | |
