Aquired traits are traits passed from the parents to the offspring. This means that aquired traits must be inherited. The parents do this to the offspring by bringing the traits into the offspring's DNA. The other kind of traits, learned traits, must be aquired by performing an action. Learned traits are not inherented and must be learned. So yes, inheritance is in your genes.

Inherited traits, like for example, your eye color, do come from your genes. However, there is a lot of luck involved too. If one of your parents had blue eyes and the other brown, there is a percent chance of having blue or brown eyes, but the chance is higher for brown.

Other factors include the environment around the DNA that can influence it. A cosmic ray from outer space can hit a piece of DNA and cause random changes too which is called a mutation. Scientists believe that this is a major way we evolved (if you believe in evolution), so a fish might have had a chemical or outside force cause a part of their DNA to instantly change enough so they got legs and could eventually walk, which has nothing to do with inheritance.

Inheritance is mainly dependant on genes. But there are some factors which can influence turning the genes on or off.. Imprinting also plays a role especially in behavioral aspects.

So it is not just whether the genes are present or not. It is all about activation or deactivation of genes that gives the output..
