Just want to make sure my Basic understanding of dominant genetics in ball pythons is correct. I realize that there is no way to predict exactly what you are going to get.... just humor me, and tell me if this sounds right.

So, If I am breeding a Male Spider ball python and a Female Normal ball python... and there are 8 eggs, because the normal has 2 normal genes, and the spider has both 1 normal and 1 spider gene... would the law of averages tell me that 2 of those eggs are likely to be spiders, and the other 6 would be normals without the spider gene at all?

Again, I know the eggs can all be norms, or all spiders or any other combination... but is my BASIC understanding of this dominant trait correct?

thanks,
