If a second cross is made using these offspring and results are ¾ short haired while ¼ are long haired can you now determine the exact genotypes of the parents and if so what are they?

Complete question:

In guinea pigs, the allele for short hair is dominant. All the guinea pigs areborn short-haired.  If a second cross ismade using these offspringandresultsare 3⁄4 short-haired while 1⁄4 are long-haired can you now determine theexact genotypes of the parents and ifso what are they?

The exact genotype of both the F2 parents is Ss, heterozygous for the trait hair length.
