Matt,

I Have outcrossed CB Yt Cribos with aberrations with WC and the hatchlings appear perfect. Same with BT and Unicolor Cribos.

On a side note this is also happening with certain lines of the Mussurana as well. Aberrant tail/belly scales , stunted growth, enlarged hearts .Perhaps the high metabolism Colubrids can't handle inbreeding like the Cornsnake and Ball Python can ?
