And Click on Case Two

1.   Click on the Application section.

a.   Study the gel. Why does the ivory sample contain only two bands while the other lanes (samples A and B) have multiple bands? 

b.   If an ivory sample has two alleles that are also found in a population sample, does that tell you with certainty that the ivory sample came from that population? Explain your answer.
