While we may insist that our environment influences our preferences, new research reveals that our genes also have influence over our preferences. Our genes control how much of our behavior might have a biological predisposition. This means that we might have been born to have a particular behavior or characteristic, as the Next Web details:

Research has shown genes may predispose not only our height, eye colour or weight, but also our vulnerability to mental ill-health, longevity, intelligence and impulsivity. Such traits are, to varying degrees, written into our genes — sometimes thousands of genes working in concert.
Most of these genes instruct how our brain circuitry is laid down in the womb, and how it functions. We can now view a baby’s brain as it is built, even 20 weeks before birth. Circuitry changes exist in their brains that strongly correlate with genes that predispose for autism spectrum disorder and attention deficit-hyperactivity disorder (ADHD). They even predispose for conditions that might not emerge for decades: bipolar disorder, major depressive disorder and schizophrenia.
Increasingly we are faced with the prospect that predispositions to more complex behaviors are similarly wired into our brains. These include which religion we choose, how we form our political ideologies, and even how we create our friendship groups.
