    Fascinating new study of the 270 individuals on whom the international HapMap is based:

    (From Nature, Via Gene Expression)

    Also see this newspaper story about the duplicated gene implications:

    Excellent post selfAdjoint. So, of the ~ 30,000 genes we each have, ~ 3,000 come in multiple copies (e.g., more than the 2 from each parent) and the number and type of these copies may be adaptive. If we consider the "selfish gene" hypothesis of Dawkins, we find a good match with theory and experiment--would appear Dawkins is correct, the evolutionary play has genes as actors, humans (and all life containers) are but part of the stage.

    And when you recall that there are all these genomic proteins with gene-minding functions, which are under independent selective ontrol, not to mention the non-coding, probably regulatory areas of the genome which now appear to have been selected strongly in human versus chimp evolution, and it becomes obvious that we're not in Mendel-land anymore.
