Answer:
Carrier
Step-by-step explanation:
An organism that is heterozygous and carries one dominant and one recessive allele of a gene serves as a carrier for the recessive allele. Carrier genotype exhibits the phenotype regulated by a dominant allele. The recessive allele for the gene is not expressed in them.
Example: A female carrier for hemophilia allele has genotype X^hX. She would not exhibit the disease.
