Summary Introduction
Introduction:
The traits that are inherited by the organisms from the parents are called heritable traits. Epigenetics is a method that is used to study heritable traits. It involves changes in the functioning of the genetic material without altering the

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?
Please answer this immediately. Thank you!
Specific environmental or nongenetic factors can cause epigenetic modifications. Identical twins have essentially the same DNA sequences; however, aging and significant lifestyle differences cause changes in _____ because:
Genomic imprinting
Histone modification
Chromatin structure
DNA methylation
How can you envision using this new information? Discuss how things that we do to our bodies (smoking, recreational drugs, employment environments, stress levels, eating/drinking habits, etc.) can influence genetic expression in our future child(ren).
