What are all chromosomes other than sex chromosomes called?

The term used to describe all chromosomes other than sex chromosomes is "autosomes." In humans, chromosomes are divided into two categories: autosomes, which are the non-sex chromosomes, and sex chromosomes, which determine the biological sex of an individual (XX for females and XY for males).

Autosomes carry the bulk of genetic information related to various traits and characteristics that are not related to sexual differentiation, such as physical characteristics, health predispositions, and other inherited traits. Humans have 22 pairs of autosomes, making a total of 44 autosomes, alongside 1 pair of sex chromosomes.

Alleles refer to different forms of a gene that can exist at a specific locus on a chromosome, representing variability for a trait but not the actual chromosomes themselves. Genotypes describe the genetic makeup of an organism, including the alleles present, while phenotypes are the observable characteristics resulting from the expression of those genotypes. Therefore, "autosomes" is the correct term for the chromosomes in question.
