In lanes 8 and 9, the DNA analyst loaded DNA fragments from himself (Bob) and his wife (Anne). Notice that Bob and Anne each have 2 bands in their respective lanes. At any given DNA locus, most people have two bands. Sometimes they only have one band and sometimes they actually have three.
Also notice that like Fred and Norma, Bob and Anne do not share any bands at this DNA locus. Although Bob's top band is close to Anne's bottom band, they are not close enough to consider them a match.
