Why it matters
Genotype describes the genetic information being examined. A report might describe just one position, a panel of markers, or a much broader set. Knowing that scope helps a reader understand what was tested and what remains unknown.
A practical example
Imagine a file that records two versions of a marker for each participant. Those entries are genotypes. The file does not need a complete genome to support useful comparisons between records.
An important distinction
A genotype is not a diagnosis or a complete description of a person. Interpreting its significance may require other variants, environmental context, family history, and evidence about the particular condition or trait.
