speaking of genetics, something bugs me about Narcissa

Note: if you're a fan of wacky and crazy theories, then scroll right to the
end.

There's something that's very off, to me, about Narcissa Malfoy nee Black.
Actually, it's the "nee Black" part, more specifically the "Black" part and
even more specifically the lack of black. In other words, why is Narcissa a
blonde?

When that fact was first introduced in GOF (it's mentioned in the Canadian
edition at least), it didn't bother me. At that point, all I knew about
Narcissa was that she was Malfoy, and the fact that there are few wizarding
families made it possible that she was a Malfoy by birth as well as
marriage.

But now we've been told she's "Malfoy nee Black" and every other black we've
seen was a brunette, right? I know a forum where people started a whole
"what if Snape is a black too?" theory based just on hair colour.

Moreover, Narcissa's sister is a brunette. Do genetics allow for full
siblings to have black and blond hair?

I think Narcissa was born a brunette, I think her hair was magicked blonde
when she joined the Malfoy clan. I have even more fun thinking that she,
like her niece, is a metamorphmagus who morphed her hair blonde.

I also have a completely wacky theory that says there were only two Black
sisters, not three. Andromeda strayed, married a muggle, gave birth to
Nymphadora, was captured by her family, got her memory modified, her named
changed, her hair recoloured and married off to Malfoy.

Hmm...
