Genera of non-algebraic leaves of polynomial foliations of $\mathbb C^2$

In this article, we prove two results. First, we construct a dense subset in the space of polynomial foliations of degree $n$ such that each foliation from this subset has a leaf with at least $\frac{(n+1)(n+2)}2-4$ handles. Next, we prove that for a generic foliation invariant under the map $(x,y)\mapsto(x,-y)$ all leaves (except for a finite set of algebraic leaves) have infinitely many handles.
