AP Bio genetics problem

In mice, long tails (L) are dominant to short tails (l).  Straight whiskers (S) are dominant to curved (s).  The genes are unlinked.  Two mice are bed many times.  The following is a compilation of the F1 data from each mating.
40 long tail, straight whisker          16 long tail, curved whisker
45 short tails, straight whisker       12 short tail, curved whisker
What are the most probably genotypes of the two parents?  Show your reasoning.

This is a type of question that I am having problems with in my AB bio class.  Can you please help me to understand how to go about solving this?
