Scientists are studying the chromosomes from a fruit fly and determine that two genes, labeled A and F, are found on two separate chromosomes. They draw a diagram, shown below.



The scientists cut the DNA into the A and a alleles, and into the F and f alleles. The scientists believe that the gene coding for the trait labeled A is smaller in size than the gene for trait F.

If this is true, what should the scientists expect to see after running gel electrophoresis on the DNA fragments?


The DNA coding for trait A will travel slower on the gel than the DNA coding for trait F.


The DNA coding for trait F will travel faster on the gel than the DNA coding for trait A.


The DNA coding for trait A will travel further on the gel than the DNA coding for trait F.


The DNA coding for trait F will travel further on the gel than the DNA coding for trait A.
