Is behavior determined only by our genes? This seems a little too absolute, but it is a valid questions. How much of who we are is determined by our genes (I'm including epigenetic parts in this)? There are certain genes that we know are responsible for intelligence, strength, sexuality, and so on. How much is determined by genetics?

Expert Solution
Step 1

Introduction :-

Epigenetics is the study of heritable changes in gene expression that occur without changes to the underlying DNA sequence. Epigenetic modifications can influence gene expression by altering the way in which DNA is packaged and wrapped around proteins called histones. This can either make it easier or more difficult for the cellular machinery to access and read the genes, thereby changing the rate at which those genes are expressed.
