DNA Genotyping Now Only $99

 23andMe is a DNA analysis service providing information and tools for individuals to learn about and explore their DNA. You give them a saliva sample and they run it through a machine to provide a report on your genotype – the data is also used anonymously for other projects requiring large amounts of DNA data. They used to charge several hundred dollars plus a yearly subscription fee, but due to new funding they have lowered the price to a one-time fee of $99 plus shipping cost for the collection kit.
