There really are new insights into our genetic variants on an almost
weekly basis. We all have different gene variants on certain DNA
segments that determine which foods keep our weight down and which make
us sick. There are millions of gene variants and, according to Science,
the world’s most prestigious scientific journal, the discovery of this
unexpectedly large variation in the human genome was the biggest
scientific breakthrough of 2007, i.e. even more significant than the
findings made in nanotechnology, aerospace and other hi-tech fields that
year.
The latest discoveries of gene variants include the MHC
genes. They determine body odors and powers of sexual attraction. A
Boston company actually offers a professional dating service based on an
analysis of this gene segment. Initial studies confirm that people have
a clear preference for a partner with certain MHC genes.
