..However, some studies have suggested that this number could be reduced if the individual spatial coordinates are taken into account in the analysis...
- Analysing georeferenced population genetics data with Geneland: a new algorithm to deal with null alleles and a friendly graphical user interface
Centre for Ecological and Evolutionary Synthesis, Department of Biology, University of Oslo, P O Box 1066 Blindern, 0316 Oslo, Norway
Bioinformatics 24:1406-7. 2008
..We show by simulations that the presence of null alleles can affect the accuracy of inferences if not properly accounted for and that our algorithm improve signficantly their accuracy...
