Restriction maps are linear (or circular) representations of specific cleavage sites separated by precise distances on DNA
If a particular genetic locus had a point mutation, would you expect it to have the same or different restriction map than the wild-type allele?
What will be an ideal response?
Ans: It depends on where the point mutation was located. If it did not fall within the target sites for the restriction enzymes used for mapping, the maps would be the same. If the point mutation was located in a target site for a restriction enzyme, then that site would not be cleaved and the maps would look different.

Answer the following statement true (T) or false (F)
The reduced-bony-armor allele of the Eda gene is present in only about 1% of marine populations, but is predominant in freshwater populations of stickleback fish. What can we conclude?
_____ Bony armor increases fitness in the marine environment, but reduces fitness in the freshwater environment. _____ Freshwater fish with more bony armor have higher fitness than freshwater fish with less armor. _____ Bony armor is an environmentally-controlled trait, not a genetic trait. _____ The allele arose after the divergence of freshwater sticklebacks. _____ The freshwater environment caused a high rate of mutation in the DNA.
