Figure 2From: Genotype calling in tetraploid species from bi-allelic marker data using mixture modelsSNP showing a large gap. For this SNP (PotSNP192) the signal strength of the b allele is smaller than that of the a allele, resulting in a non-central position of the duplex peak and a wide gap between the nulliplex and simplex peak.
