  Through the genes in the DNA.

  Hi!
  This is a really interesting question, I haven’t thought about it before.
  
  Behaviors that are closely controlled by genes with little or no environmental influence are called innate behaviors. These are behaviors that occur naturally in all members of a species whenever they are exposed to a certain stimulus. Innate behaviors do not have to be learned or practiced.
  I think that, as for every gene in the genome, an individual will get one copy of the gene from mom and the other one from dad.
