(a) Presence of a gene

(b) The number of repeats

(c) The location of the gene

(d) The methylation state of the gene

The question was asked during an interview.

My question is from Dynamic Mutation and Anticipation in section Nuclear Export & Post Mendelian Genetics of Cytogenetics

Answer 1

Right choice is (b) The number of repeats

Easy explanation: Dynamic mutation is the function of the number of copies of a particular gene present in an individual. The replication product of a dynamic mutation will usually have a different likelihood of mutation than its predecessor.
