What term refers to the location of a gene on a chromosome, identified by the chromosome number and its position?

Explanation:
The term for a gene’s specific address on a chromosome, identified by the chromosome number and the position along that chromosome, is locus. This precise location allows scientists to map where a gene sits and track how it is inherited or linked to traits, such as noting the BRCA1 locus on chromosome 17 at 17q21.31. The other terms refer to broader concepts: autosomes are the non-sex chromosomes, a karyotype is the full set of chromosomes arranged in order, and sex chromosomes are the X and Y that determine sex.
