A segment of DNA on a chromosome that codes for a specific trait is called:

Explanation:
A gene is a specific stretch of DNA that carries the instructions to make a product, often a protein, which influences a trait. Genes are located on chromosomes, so a segment of DNA on a chromosome that codes for a trait fits this definition precisely. A chromosome is the larger structure that contains many genes; DNA is the chemical that makes up genes and chromosomes; a trait is the observable characteristic produced by gene activity. For example, a gene for pigment production on a chromosome can affect eye color. So the described segment is a gene.
