Blackett Family DNA Activity

Problem 5: Hint

Are any of the other unknowns tested related to each other? If so, which ones?

At times, there could be a chance that an unrelated individual could contain a match for the individual being tested. However, the chance that an unrelated individual will share the same band match on a different probe is not as common. For example, an unrelated individual might share a sam band with Bob Blackett. If one examines other loci, the chance of that shared allele decreases if they are not related.

For this problem, determine if any of the unrelated individuals share identical bands. Score the autorads per loci. Then compare all related loci together. Chances are that you will observe matches for the same loci. However, matches between different loci are not as common.
