Answer

### Step-by-Step Solution:

1. **Understanding the Term "Autosome":**
- An autosome refers to any chromosome that is not a sex chromosome. In humans, these are the chromosomes that do not determine the sex of an individual.

2. **Identifying Chromosome Types:**
- Chromosomes can be categorized into two main types: autosomes and sex chromosomes (also known as allosomes).
- Autosomes are involved in the general body functions and traits, while sex chromosomes are specifically involved in determining the sex of an organism.

3. **Human Chromosome Count:**
- Humans have a total of 23 pairs of chromosomes, which equals 46 chromosomes in total.
- Out of these, 22 pairs are autosomes, and 1 pair consists of sex chromosomes (XX for females and XY for males).

4. **Conclusion:**
- Therefore, the correct definition of an autosome is "chromosome other than sex."

### Final Answer:
An autosome is a chromosome other than a sex chromosome.
