In genetics, the concept of "carriers" typically applies to recessive traits rather than dominant traits. A person who carries a recessive allele for a genetic trait will not show the trait themselves (since they have one dominant allele that masks its expression), but they can pass the recessive allele on to their offspring.
For a dominant trait, if an individual has one dominant allele (represented as "A"), they will express the trait; they do not carry it in a hidden form as they would with a recessive allele. Therefore, a person cannot be a carrier for a dominant trait—they either express the trait or they do not possess the dominant allele at all (and would be homozygous recessive, represented as "aa").
In summary, for dominant traits, individuals either express the trait (if they have at least one dominant allele) or do not express the trait at all (if they are homozygous recessive).
