  hi there
  we know that phenotypical characters are controled by genotypes then i want to know that in case of animals and especially in the case of insects as they undergo metamorphosis what happens with DNA/gene structure does it remains as it is during entire life or some DNA/genes follow some sort of change with respect to growth,metamorphosis and other changes

  DNA itself is intakct when metamorphosis is ocurre, becouse metamorphosis is part of insect phenotipe that determinate within the DNA. So, during metamorphosis only gene antivation/inactivation pattern is change.

  The study of this activation and inactivation of genes is known as epigenetics. You can find out a bit about it on this page:
