Epigenetic changes may be encodedin development, or they may be produced by environmental factors. From the given examples, question is asked to identify the modifications that areencoded in the development, and modifications that are produced by environmental factors. a) Imprinting of Igf2 gene in mammals. b) Development of queen and worker honeybees. c) X-chromosome inactivation in mammals. d) Development of cancer. Introduction: Epigenetic changes occur in development; these changes are reversible. Mainly, non-coding RNA and transcription factorsare involved in these processes; they recruit some proteins which carry out modification on DNA i.e. silencing and expression of specific coding sequence. It is an important event that inhibits the unnecessary expression of protein.
