Suppose you ran gel electrophoresis on individuals with length polymorphisms (such as STRS). Asia's sample has one band that migrates 5.5cm, and Jose's migrates 4.5cm. Who has the larger allele? It is not possible to determine this based on the data given. Jose They are the same size Asia

Gel electrophoresis: Suppose one of the bands in your lane migrated to the same distance as that of another classmate, while all other fragments between your sample and his differ in length. a) How is this possible? b) How would you find out if DNA fragments appearing identical in length (on this gel) are the same or different?

In humans, EcoRI site polymorphisms distinguish three wildtype alleles and one mutant allele (a through d, shown in red) for an autosomal recessive disease. In the figure shown here, each person's RFLP profile is shown directly below that person in the pedigree. Provide RFLP patterns for each allele represented in this family, consistent with the gel profile, indicating the location of the probe and restriction sites that yield the bands seen on the gel.
