According to the gel electrophoresis results, which suspect left DNA at the crime scene?

• Suspect A

• Suspect B

• Both Suspect A and Suspect B

• Neither Suspect A or Suspect B

In gel electrophoresis, DNA is separated based on

• The length of the restriction site on the DNA strand

• The size of the DNA fragments

• The number of species represented in the DNA sample

• The size of the cell from which the DNA was removed

According to the gel electrophoresis results, which child is most likely the biological child of this dad?

• Child 1

• Child 2

• Both child 1 and child 2

• neither child 1 or child 2
