The first thing you have to know is, for each color factor,
an individual cocker can have only two (2) genes 
(regardless of the number of genes that are reported for this factor).
second: a cocker can pass on only one of its genes of each color factor 
to any particular puppy (one from sire and one from dam)
third: each gene of either parent's pair are passed on to the next generation randomly (see above second thing you have to know)
fourth: is the difference between dominant and recessive.
A dominant is pretty self explanatory, it overrides a recessive. 
It doesn't allow a recessive to be seen. 
A recessive can only be seen when any individual cocker has two copies of that recessive gene
