Snips about SNPs: Taste Receptors

Do you love dark chocolate and coffee? Both have bitter flavors that some people can taste – and others cannot! We have a bunch of different genes that code for other taste receptors. So different genetic variants of those taste receptor genes mean that foods don’t taste the same to everyone.
