Explanation:

Hairy phenotype in guinea pigs is typically dominant. Dominant phenotypes can result from either homozygous dominant (HH) or heterozygous (Hh) genotypes, as the dominant allele masks the recessive one. Visual inspection only shows phenotype, not the underlying genotype.

Answer:

Hairy guinea pigs can be HH or Hh.
