Verified step by step guidance1
Understand that the question is asking for the term that refers to a segment of DNA on a chromosome responsible for coding a specific trait.
Recall that a chromosome is made up of DNA and proteins, and contains many segments that carry genetic information.
Identify that a 'gene' is the fundamental unit of heredity, defined as a segment of DNA that codes for a particular protein or trait.
Differentiate the other options: a 'chromatid' is one half of a duplicated chromosome, an 'allele' is a variant form of a gene, and a 'centromere' is the region where sister chromatids are joined.
Conclude that the correct term describing a DNA segment coding for a specific trait is 'gene'.
