That means that both parents have Mack Snow gene? Or maybe only mother has it? Father is normal loking het tremper... oh I know if both would carry the Snow gene- then the baby should have been Super..
Just so you know the Ghost and Hypo traits are two different traits. I`m leaning towards Hypo Mack(Not Ghost which is a dominant Hypo). But without knowing the background there is no way to know for sure.
