Students have asked these similar questions

Identical twins each carry the same genome, but over time, can develop different phenotypes. How can you explain this?

If our DNA contains all the information about who we are, how can something that does not involve changing the gene sequence cause changes in phenotypes? Describe briefly how these changes happen.

You find a person that has a new allele that is not found in DNA samples taken from skin cells of the mother or the father, suggesting that the mutation arose during the formation of the gametes that formed this person. Is it more likely that the mutation was present in the sperm or the egg that formed this person and why do you believe this is the case?”
