A gene located on a non-sex chromosome is described as what?

• A. Sex-linked gene
• B. Autosome
• C. Genome
• D. Karyotype

Answer: (B)

Autosomal genes are located on non-sex chromosomes, called autosomes. In humans there are 22 autosome pairs that carry most genes, while the sex chromosomes (X and Y) carry genes related to sexual characteristics. Because autosomes are present in two copies in both males and females, these genes typically follow Mendel-like inheritance patterns and show similar chances of appearing in offspring regardless of the child’s sex. In contrast, sex-linked genes reside on the sex chromosomes and often display different inheritance patterns between males and females. The genome is the full set of genetic material, and a karyotype is the visual display of an organism’s chromosome set. So a gene located on a non-sex chromosome is described as autosomal.
