# Synthetic Teaching Genotypes Dataset

This file is synthetic. It does not represent a person and is not derived from a private genome.

Purpose:
- Teach the structure of commercial raw genotype CSV exports.
- Demonstrate columns such as RSID, CHROMOSOME, POSITION, and RESULT.
- Provide examples of heterozygous calls, homozygous calls, no-calls, sex chromosome or mitochondrial-style single-letter calls, and insertion/deletion-style representation.

Format note:
- Commercial raw genotype exports commonly provide marker identifiers, chromosome labels, positions, and observed genotype calls.
- Delimiters, header names, no-call notation, genome build, and strand conventions can vary by source laboratory.

Important limitation:
- The `rsDemo*` identifiers and positions are teaching placeholders.
- Use this dataset for data-literacy exercises only, not biological interpretation, database lookup, or clinical reasoning.
