In Gel Electrophoresis, is the 'smallest fragment of DNA' the fragment of DNA that occurs the least when using gel electrophoresis on a family?

Question

If I'm interpreting your question right....the smallest fragment of DNA has the least amount of bases - it travels the farthest through the gel as a result of its small size.

The amount of DNA is reflected by the intensity of the bands; i.e., the more DNA there is, the brighter the band will be - when looking relative to one size. My understanding is that when you compare band intensities of differently sized-fragments, you cannot necessarily conclude which fragment has more DNA. Perhaps @blues can verify/elaborate on this.

Nah it was something else I meant but I think I got it. It's just that I can neither attach a file I'd like to and drawing this is just too complicated : p
