Genomic Prediction featured in the November 9, 2019 issue of The Economist
"Genomic Prediction is, however, offering something more wide-ranging. It is screening embryos for almost 1m single-nucleotide polymorphisms (snps). These are places where individual genomes routinely differ from one another at the level of an individual genetic letter. Individual snp differences between people rarely have much effect. But add them up and they can raise or lower by quite a lot the likelihood of someone suffering a particular disease. Generate several embryos and snp-test them, then, and you can pick out those that you think will grow up to be the healthiest."
