  • Fate of new genes cannot be predicted
    New versions of genes, called alleles, can appear by mutation in populations. Even when these new alleles turn the individuals carrying them more fit to survive and reproduce, the most likely outcome is that they will get lost from the populations. The theory on this topic is 90 years old and has become the cornerstone of modern population genetics, with studies on adaptation to novel ...

  • No Broccoli For Us, Thanks
    If broccoli makes you go 'blech!' the levels of mRNA expressed from your TAS2R38 bitter taste receptor gene may help explain why. Researchers from the Monell Chemical Senses Center and New York University report in the American Journal of Clinical Nutrition that the expression levels of the two alleles of the TAS2R38 taste receptor gene are associated with being able to taste bitterness and ...
