What Is the Meaning of the "Pure-Blood Mania" in Harry Potter?
Back in the forties. Many Jewish people, as you are probably aware, were targeted by the Nazis. They used a similar method as in Harry Potter by that one single Jewish person in a family tainted the family line. Similar terms were used as well, Half Blood, Pure blood, etc. In regards to Harry Potter. Those that are pure bloods, i.e. with both magical parents, are considered to be the best and that muggle borns, so those with ordinary parents, not magical, are considered dirt and the scum of the earth because they do not have the same blood line as pure bloods. However, pure bloods are really a very rare thing. Many serious pure blood people married muggles, the Black family tree is evidence of this. I believe it is Ron Weasley who remarks 'It's rubbish, everyone is half blood or less these days, if we hadn't of married muggles, we'dve died out.' He is quite right of course and *spoiler warning, though if you haven't read book 7 by now, shame on you!* Harry's own children fall into this trap. Harry as a Half Blood and Ginny as pure blood mean that His children are three-quater bloods. But it is of course debatable whether you call them pure bloods or half bloods. Then again, who wants an pure... pure blood wizarding society. You'd have to start marrying your cousins and thats not really a good idea.
Ron Weasley bloodline?
yes, Ron and Ginny are siblings therefore their children are cousins.
In the original series it isn't described but in the new play, Harry Potter and the cursed child, it's alluded to in this waySo from this we learn that, Ron was so drunk in their marriage the first time around, that he didn't even take their marriage vows soberly. And yeah they married young, so I guess 1–2 years after the events of Book 7. So maybe we will have a proper description of their second marriage err I mean marriage renewal of Rowling chooses so. As unfortunately since even Ron doesn't remember the first one, I don't think we readers would get a chance of having a description( I am pretty sure Hermione would have remembered it accurately though).
That is going to depend on what you mean by pureblood.Assuming wizards had the same genetics of Muggles, mitochondrial DNA will be inherited down the female line and the Y chromosome will be inherited down the male line. Those can be followed through the family pedigree.Humans have 23 chromosomes including the X and Y (male and female) chromosomes. The non X and Y chromosomes aggregate apparently randomly. If there was a Muggle family five generations ago then the risk of having a Muggle chromosome is 1/32. You could still have a Muggle chromosome or several, but it gets hard to sort out.To make things more complicated, apparently chromosomes swap pieces among themselves in the formation of gametes..In Louisiana in the 19th century they identified people as black if they were "octaroon" or 1/8 black.If you can identify an unbroken line of females or an unbroken line of males then you can identify the mitochondrial chromosomes or the Y chromosome, respectively.I think the question about whether the Weasley's cared about bloodline had more to do with attitude than genetics.One of my aunts traced our family history back to eighth century Denmark. Does that make me a Viking?It makes the whole idea of race rather stupid, doesn't it?
Do the purebloods in Harry Potter practice incest?
Some do, yes. There are so few purebloods that they need to do this in order to stay pure. There are other pure bloods though, like Harry's father, who don't care about keeping their bloodlines pure and married someone otherwise pureblood, like Harry's mother, and isn't related to. Another example of this would be the Weasley's. While pure blood, any concerns as to who their children married had nothing to do with blood status. But some families were so obsessed with keeping the family 'pure' (like the Black family, Sirius and Andromeda being the few exceptions) that they disowned anyone that dared to marry someone less than pureblood. So yeah, a lot of them practice incest, but I don't think they go as far as allowing relationships between first cousins and brothers and sisters.
In harry potter, what does blood traitor mean?
Hey! Well it is usually "Pure Blood" people who call people "Blood Traitors." Blood traitors is a name for pure blood people who do not believe in the old ways of "Pure Blood families only" and that pure bloods are the only onse worthy to study magic. However families such as the Weasley's who are pure bloods do not believe in this. Mr Weasley works for the ministry in the muggle artifacts office, which some families such as the malfoys dissaproved off. Ron is best friends with Hermionie, who is muggle born, and so Kreacher would call him a blood traitor. I hope this helps. Good question. x
Half-blood. Purebloods have all four wizard-born grandparents. Wizard-born meaning born to at least one wizard (ie: half-bloods and purebloods). Harry and Ginny’s kids have 3 wizard-born (pureblood) grandparents (James, Arthur and Molly) and one muggle-born grandmother (Lily).But if Harry and Ginny’s kids married a pureblood or half-blood with both wizard-born parents, their grandchildren would be pureblood. For example: if James II marries a pureblood, his kids would have 4 wizard-born grandparents (since Harry is wizard-born).Another example: Teddy Lupin is half-blood (because he has two muggle/muggle-born grandparents), but his kids with Victoire Weasley would be purebloods. This is because all four of their grandparents (Remus, Tonks, Bill and Fleur) are wizard-born wizards (at least half-blood and above).But this is technical. Fanatic people would only consider people with no traceable muggle heritage as purebloods.
Even though Harry’s father (James) was a pure-blood, Harry himself is a half-blood because his magical mother, Lily Evans, was a Muggle-born.Basically, a half-blood is any magical person who has a mixture of magical and non-magical ancestry. The most widely-given explanation is that a half-blood is any witch or wizard who has one or more Muggle-born or Muggle parents or grandparents.With half-blood status, it doesn’t matter which side of the family (father, mother, or both sides) has the Muggle blood. Harry, Severus Snape, and Tom Riddle (later known as Voldemort) were all half-bloods: Harry because his mother was a witch whose parents were both Muggles, and Snape and Tom because their mothers were pure-bloods but their fathers were Muggles. Likewise, the offspring of both Ron Weasley and Ginny Weasley (who are pure-bloods) are all considered to be half-bloods because Ron’s kids have two Muggle grandparents through their mother (Hermione Granger, a Muggle-born), and Ginny’s kids have a Muggle-born grandmother through their father (Harry Potter).According to J.K. Rowling, half-blood wizards are the most common type among the three purely human magical blood-status types, making up about half the population of the Wizarding community. Next are Muggle-borns (25% of the magical population), with pure-bloods accounting for only 10% of the total. The other 15% are mostly mixed-species individuals (such as Fleur Delacourt, who was half-Veela; Hagrid, who was half Giant; and Professor Flitwick, who was one-quarter goblin), and a few are Squibs (non-magical individuals who have at least one magical parent).Also according to J.K. Rowling: there are no true pure-blood wizards. Although there may be a few families who genuinely have only pure-blood members in recent generations and whose pure-blood lineage stretches back for a few hundred years, those families still have half-blood, Muggle-born, or Muggle ancestors somewhere in the roots of that family tree. The more snobbish “pure-blood” families simply choose to ignore this fact and/or selectively prune their family trees by removing any mention of their half-blood, Muggle-born, Muggle, or Squib relatives from their genealogical records.)
The child will be a half-blood. Rather than the blood status of the individual parents, their entire ancestry is taken into account when blood status is given.For example, both James and Lily and magical, but Harry is still a half-blood. This is because Lily's ancestry is full of muggles.Similarly, the children of Harry and Ginny will also be half-bloods, since Harry has muggle ancestry on his mother's side.Of course, only direct ancestry is taken into account - that is your parents, grandparents and so on. It doesn't matter if your aunt or uncle or cousin are muggles or married into muggles. Arthur Weasley has a second cousin who is a muggle, but the Weasley's are still considered as pure-blood since they are not directly related.For example, if Sirius Black married some distant Weasley cousin, his child would be pure-blood. Even though the Black family tree has half-bloods in it (Nymphadora), it wouldn't count as she is not directly related to Sirius.So Pureblood + Pureblood = Pureblood (Ron Weasley).Pureblood + Half-blood = Half-blood (Albus Severus Potter).Pureblood + Muggle = Half-Blood (Harry Potter).Half-Blood + Muggle = Half-Blood. (Though I don't known an example).Muggle + Muggle = Muggle-born (or the more vulgar 'Mudblood') (Hermione Granger).
Thinking about it, the Parseltongue = Heir of Slytherin is meaningless, and likely propaganda spread by blood-purists.Firstly, I think almost the whole of Wizarding Britain would be descendants of all the founders. With so many centuries, and such a small community, everyone would be related to everyone if you examined closely enough.The second thing is that blood-purists wanted to keep a monopoly on the traits of Slytherin, their hero. So from their point of view, Parseltongues were 'obviously the right stuff’.But part of the way that they were able to keep it a private language was by convincing the world at large that 'knowing' it was a hereditary trait and so trying to learn it is pointless.For wizards, I don't think Parseltongue is any more difficult to learn than all the Latin that they pick up at Hogwarts.Ron needed to repeat something he heard, tried, and found he could, because the mere 'fact' he couldn't wasn't going to dissuade him.It's a repeated theme in the series that the wizarding community at large is in a state of stagnation, in part because of misconceptions the world had about itself.
