Unstable transmission of the chromosome 5 macrosatellite. Inheritance of the chromosome 5 macrosatellite through three generations in three CEPH Utah pedigrees. (A) CEPH-1331, (B) CEPH-1333 and (C) CEPH-1345. Members of each family are indicated above each blot in the pedigrees and the numbers given are the Coriell GM0- ID for each member of the family. The size of the hybridizing fragments are given to the left and right sides of the blots. The blot in image (B) comes from two separate blots for which DNA was separated under different conditions to ensure resolution and visualization of the largest and smallest arrays. The asterisk indicate alleles of altered size.
