I don't think nature vs. nurture is a good way of thinking about complicated biological phenomena. For example, take height. We know from recent GWAS[0] that many genes are associated with height[1]. We also know that poor nutrition in early life will lead to severe stunting, regardless of genetics.
My model for thinking about these things is genes delimit the scope of possibilities, environment (some of which is prenatal or early childhood and very hard to change) determines what possibilities turn into reality.
