Sure. Heterzygous is referring to having two different alleles at the same gene; if you sequence the gene from a homoZ you could only get one uique sequence (say, ATG) but if you sequence it from a heteroZ then you get two different sequences (say ATG and ACG). In the albino example, you would probably sequence the tyrosinase gene in a normal and then in a albino to get the sequence of the two different alleles. Then, if you sequence the possible hets you would get only the functional (normal) copy from the HomoZ but both the normal and the mutatnt copies from the hets.
But thats all assuming you have a lot of time and money to set up the tests. Its really not practical to do in snakes (yet).
Hope that made some sense,
