Question

what is true about a dominant trait? it is expressed in the phenotype. it is represented by a lowercase letter. it is only visible if two alleles for the trait are present. it is not visible in a person who is heterozygous.

Explanation:

In genetics, a dominant trait is always expressed in the phenotype when present. Dominant alleles are typically represented by uppercase letters. A dominant trait is visible in heterozygous individuals (where one dominant and one recessive allele are present) and does not require two copies to be visible.

It is expressed in the phenotype.
