6. A short-tailed mutant of mouse was discovered. Multiple crosses of this mouse to normal mice produced 27 normal, long-talied mice and 25 short-tailed mice. A series of crosses among short tailed mice were made and and 21 short-tailed mice and 11 long-tailed mice were produced? Study these results and determine which phenotype is dominant and explain the ratios observed with regards to the genotypes of the parents in each cross.

Is this a case of epistasis?

I'm sorry but I'm really lost? How do we know the genotype of the short tailed mice is SL and not SS?
