blech!!! I wouldn't use quantitative PCR to do something that's easily
done conventionally!

Also, my experience with microsatellites has shown me that different sized
alleles amplify...differently. Assuming you're using microsatellites,
you'll have to take this into account, because you're likely to find that
smaller alleles amplify more readily than large ones - and if you're
pooling samples, you might lose the larger alleles all together because of
the "competition" - the smaller alleles (even if they're only smaller by a
few nucleotides) will have the amplification advantage.
