If a person has a recessive allele for a disease and that allele is masked by a normal dominant allele, they are heterozygous for the disease. This person is called a "carrier" because they carry the recessive allele but do not have the disease themselves. They can pass the recessive allele to their offspring, but the offspring will only have the disease if they inherit two copies of the recessive allele (one from each parent) and do not have a dominant allele to mask it.
