Chromosomes are made of condensed coils of DNA. Genes are segments on a chromosome that carry the code for a specific trait. Alleles are contrasting forms of a gene. Dominant means that a particular trait will be visible. Recessive means that a trait will be hidden (unless it is paired with another recessive gene). A trait is how the gene is seen. For example, eye color is a trait.
