Answer:
In genetics, dominant and recessive refer to the two different versions, or alleles, of a gene. A dominant allele is one that is always expressed, or "seen," in an organism's physical traits. A recessive allele is one that is only expressed when two copies of the allele are present in an organism. This means that if an organism has one dominant and one recessive allele for a particular trait, the dominant allele will mask the expression of the recessive allele.
