When we look to the past and to our presumed genetic ancestry to understand and explain our own behaviors today, it is not much better than astrology. The genes of your forebears have very little influence over you. Unless you carry a particular disease that has passed down the family tree, the unending shuffling of genes, the dilution through generations, and the highly variably and immensely complex influence that genes have over your actual behavior mean that your ancestors have little sway over you at all.
