<em>The correct option is 'this guinea pig could be homozygous dominant (HH) or heterozygous (Hh).'</em>
Explanation:
When both the alleles of a gene are the same then they are termed to be homozygous. If a gene possesses two different types of alleles then it is termed as heterozygous.
A dominant allele is the one which can suppress the effect of a recessive allele. A recessive allele is the one which gets masked by the dominant allele.
For a dominant trait to occur, an organism can either be homozygous dominant for that trait or it can be heterozygous for the trait.

calling the poison control because the mother should call the poison control in
order to ask the steps that she should start or take when treating ingestion.
