Chromosome that is not a sex chromosome Autosome Homologous pair Sex Chromosome Chromosome

## Step 1: <br />Understand the question. The question is asking for the term that refers to a chromosome that is not a sex chromosome.<br /><br />## Step 2: <br />Review each option. <br /><br />- An autosome is a chromosome that is not a sex chromosome. It carries genes that are not directly involved in determining the sex of an individual.<br />- A homologous pair refers to two chromosomes, one from each parent, that are similar in length, gene position, and centromere location. This term does not specifically refer to a chromosome that is not a sex chromosome.<br />- A sex chromosome is a chromosome that participates in the determination of the sex of an individual. This term is the opposite of what the question is asking for.<br />- A chromosome is a long, continuous thread of DNA that consists of numerous genes and is responsible for the determination of the characteristics and traits of an organism. This term is too broad and does not specifically refer to a chromosome that is not a sex chromosome.<br /><br />## Step 3: <br />Based on the definitions, the correct answer is "Autosome" because it is the only option that specifically refers to a chromosome that is not a sex chromosome.
