These are from a ghost male and amel/frosted female. I was orignally expecting all normals, but so far there isn't a single normal one. It looks like I've got snows, anery, and amel. From another cross with an anery female with my ghost male I know he is het amel because their clutch produced 1:4 snows. So I was then expecting half normal and half amel, but I guess the amel female must be het for anery?

The pictures are too dark for me to see what you've got in this clutch. Can you describe the babies, and how many you have of each morph?

That would seem to be the logical conclusion. With only six babies, the clutch is too small to yield statistically representative ratios of each morph, it is pure chance that you have no "normals", and you could just as easily have ended up with three or four normals, and only two or three other morphs.

If you had a much larger number of offspring, the ratios would be:

1:4 snow het hypo
1:4 anery het hypo & het amel
1:4 amel het ghost
1:4 het hypo & het snow (normal phenotype)

Ok, so far I have 5 amels, 5 snow, 2 normals, 1 anery crawling around; with what looks like 2 more amels and one either normal or anery still in their eggs.

Also, there is one egg that hasn't opened at all, not even a slit. It is much bigger than the others, and looks good (no brown/mold or anything like that). It hasn't dimpled yet, at least as far as I can see. How long should I wait before I do anything, or should I do anything about this last egg? I'm wondering if there might be two in that egg.

My camera is one of the first digital cameras made. I guess it's time for a new one. These were taken in nearly direct sunlight and they still look dark and washed out.

This one shows the lone anery next to one of the two normals:

A VERY NICE clutch. Congratulations!

The numbers don't agree with the statistical percentages, but I'm sure that your parent stock are of the genetic make-up that I previously pegged them to be. The male is a ghost het amel, and the female is an amel het anery. Provided that she doesn't also carry a hypo allele, the babies are as I previously stated and are all het for hypo (from their papa).

That last egg looks as though it is probably viable. It may, or may not be good, and it possibly could hold twins. Don't mess with it yet. Wait for at least another day or so, then you might consider slitting it. There are differing schools of thought on whether or not slitting is a good or a bad idea. You may want to check dicussion about it in the archives before deciding whether or not to do so.
