QF-PCR analysis of family genomic DNA samples for revealing the nature and origin of T9 mosaicism. Plots show yield of STR PCR products (Y-axis) versus allelic size (X-axis). Blue and black peaks represent 6-FAM and TAMRA labeled allelic products, respectively. The dominant paternal alleles (isodisomy 9) and the minor maternal alleles for informative STR markers D9S925, D9S1118 and D9S1121 that were inherited by the proband are denoted by symbols (*) and (+), respectively. Control marker D13S325 shows two allelic peaks indicating expected disomy 13
