There has been some discussion on the purity of blood of Severus 
Snape and what level of blood he could have had to get into 
Slytherin.  It is not clear from the books that Voldemort was in 
Slytherin, but for the sake of argument and the fact that he is 
Salazars descendent/ancestor lets assume that he is for the moment.  
We know that Tom Marvolo Riddle is a half blood, a full blood wizard 
and a muggle.  But he gets into Slytherin.  We know that the sorting 
hat wanted to put Harry into Slytherin, Salazar had no problem with 
his blood, and Harry has a full blood father and a muggle born 
mother.  But Harry is named as a half blood through out cannon by 
Draco and Voldemort.  Can we assume from this that a Wizard "tainted" 
by Muggle born blood is also regarded as a half blood?

If this is true then I feel there must be some intermediate step 
between a half blood Wizard and a Pureblood wizard.  How many 
generations would it take for a Muggleborns family to pass from half 
blood to pure blood?  Could this in-between step be known as a full 
blood wizard?  A full blood wizard is a Wizard whos parents are both 
wizards but are not half blood wizards.

For example:

A muggle (M) who married a muggle (M) can give birth to a muggle (M) 
or a wizard (W).  There was some interesting discussion about 
the "magic" gene and how it passes from generation to generation a 
while back but unfortunately I never followed it so I cannot give you 
any post numbers.  Sorry. 

This possible wizard child will be a muggle born (MB) and be regarded 
by some to be a "mud blood".  This muggle born (MB) can marry a 
muggle (M) and either give birth to a muggle born half blood (MBHB) 
or a half blood muggle (HBM).  I do wonder how many of these HBM are 
going about, no magical ability but with one parent a witch or wizard.
Or the MB can marry a full blood wizard (FB).  This child will either 
be a squib, a child of two wizarding parents (whatever their blood) 
who has no magical power, or be a half blood (HB), see Harry.  I do 
not know if the child of a muggle born and a muggle would be regarded 
as a "mud blood" or a "half blood" by the aristocracy.

Now this HB can have children with any one but as we are trying to 
marginalise the muggle blood in the child I will rule out - a muggle, 
a half blood muggle, a muggle born half blood, and for arguments sake 
a Squib.  This half blood married a full blood wizard.  I am almost 
certain that this child would be regarded as a full blood wizard.  By 
the next generation, certainly, provided the child of the half blood 
with another full blood married a full blood.

Now for those of you who didn't get any of that, I am hesitant not to 
count myself in that number, that is four generations.  Muggle to 
Muggle born, Muggle born to Half blood, Half blood to Full blood and 
once more for luck.  We know that Ernie MacMillian thinks of himself 
as pure blood through five generations of witches and warlocks (why 
not wizards one wonders?).  Could this be that after four generations 
as above there must be around five more to allow a wizard to move 
into the pure blood circle of the wizarding world?

No wonder there are so few of them and the few that there are, are 
all interbred.

Here is a little diagram of what is written above about the steps to 
become a pure blood wizard

-Muggles

Half blood Muggles
Squibs
-Muggle born

Half blood Muggle born
-Half blood Wizards

-Half blood/Full blood

-Fullblood

X number of generations

-Pure blood

Muggles are muggles plain and simple.  Half blood Muggles are the non-
magical children of a Wizard and a muggle.  Squibs are children of 
two magical parents that do not have any magical power but Wizard 
blood whether pure or not.  Muggle borns are the children of two 
muggles who have Wizard power but no Wizard blood.  A half blood is 
the child of a Muggle and a Wizard that has Wizard power but also it 
seems to be the child of a (at least full blood) Wizard and a Muggle 
born.  Full blood is a Wizard with Muggle blood but the connection is 
some number of generations back.  A pure blood is a Wizard with 
wizard blood for so many generations or more.

It seems to me that Slytherin would accept anyone including and over 
the halfblood mark.  I do sometimes wonder whether every pure blood 
that steps up to be sorted is desperately wanted by the house of 
Slytherin just to add a little variety for the inbreeds.
