Defining genetic and epigenetic variation during early development

我们都从父母那里遗传了一套基因。然而，现在我们知道，从我们在子宫里开始，基因就可以被环境关闭或打开，甚至完全丢失或获得。甚至你母亲在怀孕期间的饮食和行为都可能影响你未来的健康。因为人与人之间的差异太大了，我们正在研究双胞胎之间的细微差异，以梳理出可能影响我们基因和健康的因素。

We all began life with a set of genes inherited from our parents. However, it's now known that from the time we were in the womb onwards that genes can be turned off and on by the environment or even completely lost or gained. Even what your mother ate or how she behaved while she was pregnant could have influenced your future health. Because people are so different, we are studying the subtle differences between twins to tease out the factors that may influence our genes and our health.
