Great page for the stat people....

One nerdier step further:

For genetic probabilities of 50% on a single egg (e.g. homozygous to heterozygous)

The probability of getting exactly X of the mutation in N eggs is:

N!
-----------------
2^N * X! * (N-X)!


For genetic probabilities of 25% on a single egg (e.g. heterozygous to heterozygous)

The probability of getting exactly X of the mutation in N eggs is:

N!
----------------- * 1/(summation for i=0 to N of A)
2^N * X! * (N-X)!


N!
Where A = ------------
i! * (N-i)!


Or more simply it's the number of possible combinations of the number or morphs you want divided by the total number of possible combinations....

I'll work up a spreadsheet that gives this info and post it on our site.....interesting stuff......
