Muggleborns!

When some-one is born to two muggle parents, do they have some form of a 'magical' history as in do the parents both contain the 'magical' gene but it isn't dominant in them the same with their grandparents etc?

From what I remember, when a squib (who carries a magic gene it's just not dominant)marries a muggle and has children, the magic gene is still present in the kids. Generations after, the magic gene may reappear in the great-great-great grandchild and the kid will be known as a muggleborn.

So it only takes one squib grandparent, possilby generations back, for a muggleborn to be born.

Hope that helped ya!

Well, I might have been a C student in Biology, but the one thing I always got perfect scores in was genetics. And I think I've figured out how a Muggleborn witch or wizard comes along.

RR: this is a witch or wizard

oo: this is a Muggle

R represents the dominant gene that causes someone to be born with magic. But every now and then a Squib is born (rr). They still carry magic inside them, but it is as a recessive gene. So Squibs will inter-marry with Muggles creating this pattern:

rr+oo=ro (and any children they have will become carries of the gene as well)

But every now and then, two carriers will have a child together.
ro+ro=rr...or R (having magic when neither of the parents do)


Because the two recessive genes merged together, it creates for the recessive trait of having magic and a Muggleborn witch or wizard is born. But not all children born to them will have magic.
oo
ro
ro
rr=R
So in these situations, the chance of a Muggleborn witch or wizard being born into the family becomes one in four. All the children might have magic, only one might, or maybe none of them and they will all just be another generation of carriers.

And if they were to marry and have children with someone from a Magical family, we would see this.
RR and rr having...
Rr children, carrying one dominant gene and one recessive (but still not enough to ensure the birth of magically inferior or lacking children)



I wonder if the inbred purebloods would have been intellegent enough to understand this? *Molly stand at the front of the class, writing on the chalkboard, while the classroom of pureblood fundimentalist look on with dazed, confused looks*

F's! F's for all!
