In complete dominance, the effect of one allele in a heterozygous genotype completely masks the effect of the other. The allele that masks the other is said to be dominant to the latter, and the allele that is masked is said to be recessive to the former. Complete dominance therefore means that the phenotype of the heterozygote is indistinguishable from that of the dominant homozygote.
A gene or allele (an allele is the individual copy obtained from the parent) is a set of instructions used by the body to produce proteins. So, although we talk about genes being dominant or recessive, the reason is actually in the protein. There are numerous reasons why one may be dominant or recessive. One is that a protein results in an absence of something. That protein will be recessive, because its trait won't be evidenced unless the allele from the other parent is identical. Eye color is an example.
