Its all good. Once you get the hang of it, you will understand what we mean. Punnet squares are a good way to visualize the frequency of occurrence of a trait. One important point to realize is that the punnet square doesn't give you an exact percentage of how many offspring in a clutch will express a certain phenotype. Rather, it gives you the statistical chance that a certain allele is going to be paired with another allele in every fertilization. So in the case of breeding two BPs het for albino, both the male and female each produce sex cells that half contain the recessive gene, and half that contain the dominant form of the gene. Said another way, each parent snake has a 50% chance of passing on the recessive albino allele when each egg is fertilized. However, for the hatchlings to be albino they must have both a recessive gene from mom and dad snakes. So the statistical probability of both mom and dad passing on the recessive allele is 50% x 50% = 25%. Given a statistically large enough population, the occurrence of albino would trend towards 25%. But in smaller numbers, like those for BP clutches, sometimes the statistics don't completely pan out. You could get lucky and get all albinos, or none.
