Genetic variations within and between populations

  1. May 12, 2013 #1
    This paper asserts these two different conclusions:

    How don't they contradict each other? What exactly is "variation between populations" and "variation within populations"?

    There are likely a small number of sites that differ between populations that can be reliably used to distinguish those populations. However, there are a larger number of sites that differ within a population.

    I don't understand, can you explain it in another way?

    Overall variation may be too high to distinguish populations from each other, but that doesn't mean there can't be specific genes that are still unique to their respective populations.
