What are some of the bad effects of inbreeding on corn snakes

If all goes well with this attempt, a closer look will reveal a successful copulation in progress. Here you can clearly see that this pair knows what they are doing and soon I'll be the proud daddy of a clutch of caramel and Butter corns (the female is heterozygous for Butter)

.

We'll continue introducing the pair together for periods of a day or two at least twice per week, until the female becomes visibly gravid.

May

Many pairs are still being introduced, but most females are starting to show eggs at this time. Many will lay their eggs in the last two weeks of May, although a few will not lay until June. Determining whether a snake is gravid (carrying eggs) can be difficult, but here's a few tricks:

The first clue is a general heaviness throughout the lower half of the snake. Often, this is most visible from above and many females begin to show a 'peaked' look along the spine. This is due to body fat reserves and muscle mass along the sides being used up to produce eggs, which ride lower in the body cavity. Here you can see a gravid Crimson corn. Note the peaked look of the body below the curve, and the swelled area beginning somewhere just above the vent.

.

Lifting the snake gently off the ground should make the swelled area beginning just above the vent even more apparent. On lighter colored snakes, you can even see the white coloration of the eggs through the body wall. It is barely apparent in this Crimson corn, but I've showed you where to look!
