Where the heterozygote is indistinguishable from one of the homozygotes, the allele expressed is the one that leads to the "dominant" phenotype, and the other allele is said to be "recessive". An allele is a very specific part of a gene or chromosome that is found at the same location. In genetics, the dominant pertains to the one that determines the phenotype of an organism.

Since human cells carry two copies of each chromosome?

Different versions of a gene are called alleles. Dominant allele any allele that is always expressed in the phenotype of an organism.
