I saw on many different websites the results of breeders listed clutch by clutch.

There by I found out that the results of Spiders x normals are much lower as Pastels X normals.

How are your experiances? I´m a little bit exited because I´ll breed coming season my Spider male to nomal females.

Thank you in advance.

In both cases, each egg has exactly a 50% chance of
displaying the morph. It is a coin flop. Over the
long-run (hundreds, or thousands of babies), you would
find that half are the morph and half are normals.
In the short-run (a few clutches), anything can happen.

Chris,

thank you for your answer.

I know how the co-dominat trait works, but the breeding results of the Spiders are lower as the Pastels.

I just don´t know why because both are co-dominant traits.

I was not looking at 1 or 3 clutches, I looked at many different breeding cycles of different breeders.

This is the reason I´m confused now.

Again, thank you for your assistance. Every opinion and advice is great and welcome.

It's just an odds thing -- we have seen some people this season really hit the odds with spiders with almost all spider clutches - and some people that didn't. Same with pastels - one breeder I know got only one pastel out of a clutch of 8 but his second clutch came back pastel heavy and the third clutch fairly even - all the same father.

Please post the number of spider X normal clutches you are looking at and the total numbers of normal and spider offspring.

If it really is enough to be statistically significant and a random sample there could be any number of explanations like maybe some genetic spider offspring looking like normals or spider eggs being less likely to hatch or spider sperm being slower swimmers.
