WebIn genetics, a dynamic mutation is an unstable heritable element where the probability of expression of a mutant phenotype is a function of the number of copies of the mutation. That is, the replication product ( progeny) of a dynamic mutation has a different likelihood of mutation than its predecessor. WebAn anomalous pattern of inheritance, first identified by researcher Stephanie Sherman, in which the manifestations of a particular inherited disorder (Sherman studied Fragile X syndrome) are more marked with each passing generation of patients who are at risk of a certain mutation.
