How do naturally occurring polymorphisms in DNA sequence relate to variation in gene expression? Recent work to map genetic sources of expression variation has shown a surprising balance between cis and trans effects. Other work suggests some chromosomal clustering of genes by expression pattern. A synthesis of approaches may provide new insight in to adaptive mechanisms in evolution and the population basis of complex traits.
