My conclusion is that merging genes is essentially rolling the dice, and all you can do is try to stack the odds in your favour. There are a great many unfortunate genetic outcomes when it comes to breeding, and you can reduce the chances of many of them by reducing the level of incest in your breeding.<p>I bet you already knew this is what I meant and didn&#x27;t actually need me to spell it out for you. As an aside, I read elsewhere that you and your wife are both from Western Europe. That&#x27;s actually a lot closer than I had in mind; I said breed with someone who <i>really</i> doesn&#x27;t look like you. :)
