Donna is Sophies's mother, but Sophie does not know who her father is. She collects DNA samples from herself, her mother Donna, and three potential candidates (Sam, Harry, and Bill) who could be his father. She extracts the DNA, amplifies the locus of interest using PCR, and runs a gel electrophoresis. The results are attached.
Harry's well only produced one bar, and we are certain that no part of any sample ran off the end of the gel. What word described the state of Harry's alleles at this locus?
The well is between 50bp and 100 bp
