^ Because in the only examples we've had on TW the mutation was a result of a personality flaw that had been nurtured NOT natured.

I. E. Jackson was cold and bullish because of things that happened to him but once those things were resolved he became a werewolf.

Education became a "demon wolf" because his vengeance was nurtured by events that occurred (blinded & attacked later by his beta) so his appearance reflected his anger.

Peter gave in to his rage and anger in S1 thus his beastly appearance. In S2 & 3 he was normal looking. In S4 finale he was again giving in to his rage.

All of them still have the component that the appearance reflects personality. The key word is PERSONAL. It is a personal choice or desire not a natured or BORN one. Thus far we haven't seen any creature possess the ability to influence the sex, let alone the personality of unborn offspring.
