Microsatellite null alleles in | Effects on parentage assessment
Although we focus here on the effects of null alleles in parentage studies, it is possible that they may cause less bias in the analysis of population structure. Lehmann et al (1996) also found ‘null series’ in which multiple size classes were contained within an apparent null allele. In this case, PCR failure...
