I don't. But in addition to genetics, babies pop out of rich and poor vaginas. Socioeconomic status is a much stronger indicator for being incarcerated than genetics (not counting "male vs female"). There is also the theory that the children of prisoners grow up without fathers and are more likely to go to prison, thus perpetuating the cycle. Children that lose both parents (to imprisonment, drug addiction, abandonment) and enter foster care or become wards of the state have terrible life outcomes. Not genetic, but familial due to disrupted social support networks.
I also think that if, for example, you get addicted to heroin, and you don't have a good support network, that will be your only life until you're dead. But if you do have a good support network, you have an better chance of getting clean and staying clean.
