How does a winter white dwarf with both the marbled/merle and pearl genes look like?

[athelard]

A hamster with the marbled/merle gene from only one of the parents will be a marbled/merle, because the gen is dominant.

A hamster with the pearl gene from only one of the parents will be a pearl, because the gen is dominant.

A hamster with the marbled/merle gene from both of its parents will be a marbled/merle.

A hamster with the pearl gene from both of its parents won't be born, because the gen is lethal when inherited from both of the parents.

So what would happen to hamster that has the pearl gen from a parent and the marble/merle from another? Will it be pearl, marbled/merle, a combination or it won't be born? Or something else completely different?

Thank you for your answers.
