Unless your homozygote samples are accidentally mixed i.e.
homozygote with no defective allele 135bp
homozygote with defective allele 108bp + 25bp
heterozygote 135bp + 108bp + 25bp
Or am I missing something?
The problem with being on the cutting edge is that you occasionally get
sliced from time to time....
