I don't know much about genetics. For an arts project I'm looking for a human genome.
I read that:
Only about 0.1% of the genome is different among individuals, which equates to about 3 million variants (aka mutations) in the average human genome. This means we can make a “diff file” of just the places where any given individual differs from the normal “reference” genome. In practice, this is usually done in a .VCF file format, which in its simplest format looks something like so:
chr20 14370 rs6054257 G A 29 PASS 0|0
Where each line uses ~45 bytes, and you times this by the ~3 million variants in a given genome, and you get a .VCF file size of about 135,000,000 bytes or ~125 megabytes.
Is that correct?
Do you know a database to download a VCF file or something similar? It would be amazing if you could provide a link to the file mentioned above!
