I am interested in degree 6 genus 4 curves in $\mathbb{P}^{3}$, in other words, the complete intersection curve of a quadric and a cubic. Is there any result on the Hilbert scheme of such curves concerning:

(1) Its number of irreducible components;

(2) Singularities of the component containing smooth degree 6 genus 4 curves (is this component smooth?);

(3) How could one degenerate a smooth degree 6 genus 4 curve to other components? Like in twisted cubics case one can degenerate a twisted cubic to a plane nodal cubic with a spatial nonreduced structure on the node, I am not sure if there is similar degenerations in degree 6 genus 4 curve case since in general degenerations can be bad.

Thanks!
