Schizophrenia Genetics in Science: SNPs Are Only One Piece of the Puzzle

Genome-wide association studies, which are the source for most of the data 23andMe uses in Gene Journal (now called Health and Traits) entries, are based on the “common disease-common allele model” – the idea that many illnesses, even relatively rare ones, can be caused by combinations of genetic variations ...

The World in a Pipette: Two Studies Look at Human DNA Diversity

If you take two members of the human race at random and ask how much their genomes differ, you'll get a surprising answer: they're almost identical. On average, for every 1,000 DNA bases you have, 999 or so of them are exactly the same between you and your neighbor – and for that matter, between you and ...
