Minimizing Observer Effects in the Interpretation of Forensic DNA

Analyses of NDIS profiles would allow independent evaluation of some of the population genetic assumptions used to generate statistical weights for DNA profile matches with samples large enough to allow sensitive evaluation of population structure. Databases that have been made available for such an ...

DNA and Genealogy
... Short Tandem Repeat. Also known as microsatellite. This is a genetic marker consisting of multiple copies of a short motif, (a sequence of DNA bases). Occasionally, a microsatellite will mutate by the gain or loss of one repeat. So-called "simple" STRs have just one contiguous set of repeats; "compl ...

17.3 The Process of Speciation

They survived and reproduced. Over time, some finches from the first island may have migrated to a new island, becoming a new geogra ...
