Can you read your genes in your face?
« on: 12/08/2008 22:50:18 »
katy ororke asked the Naked Scientists:

I have a general question: I am very interested to know whether you think an individual's facial features, for example factors such as symmetry, and size of features, and the measurements between these features (akin to the mask developed recently by a plastic surgeon) show to any extent the genetic make-up of a person....and whether this could affect the selection of partners for procreation?

Apparently the waist to hips ratio of a woman shows their fertility? is there a parallel with facial characteristics? could these characteristics also give a clue to blood type? oriental diagnosis claims to diagnose illness from facial features. is there any concrete research material i could get hold of in this vein? an answer most appreciated....katy

What do you think?

Well there’s something called the “handicap hypothesis”, which discusses the effect of high testosterone levels and immunocompetence during development for males.

Prominent brow ridges, cheek bones and angular jaws indicate high levels of testosterone. Generally such features are associated with strong masculine males. However, testosterone, in high levels, acts to partially suppress the immune system. It is hypothesised that individuals that can successfully develop under the immunosuppressive pressure of high testosterone levels must have a particularly resilient genetic compliment that enables them to compensate for this.

So in that sense, masculine facial features could be used to speculate about the immune system regions of an individual’s genome…..
