When a genotype of a guinea pig is "Hh" (select all that are true)
Butoxors [25]

Answer:

One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair

One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated

Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

Explanation:

Hairy is dominant over hairless. If there was a hairless guinea pig here instead, we would know its genotype. It would be hh. Remember any time a dominant allele is present it is expressed in the phenotype, so if the phenotype is not the dominant one, we know the genotype must contain two recessive alleles.
