Are identical twins really identical?

Tuesday 18 December, 2007

To many of you who come and ask about identical twins and how genetically identical they are, this is an interesting documentary movie (less than 15 minutes) about the effect of epigenetic factors on gene expression.

The movie can be viewed here.

So, away from Shakesperian plays where two twins are separated since their birth, even in similar geographical environmental conditions, there are other factors that can make identical genes behave differently: what a pregnant woman eats can not only affect her baby’s phenotype, but also his or her genotype and even the grandchildren genotype.

Enjoy the show while it lasts (I don’t know how long it will be available online)…
