There are several types of magical bloodlines – however, contrary to what many witches and wizards believe, one is not better or more superior to the other. Below is some information about each bloodline for educational and informational purposes.
Pure-blood
Pure-blood witches and wizards are those who come from families with no Muggles and all have magical abilities. In reality, most pure-blood families do have some Muggle ancestry at some point in their history (Pure-blood, n.d.).
Many pure-blood families maintain prejudice, claiming that their bloodline is “superior”, and will even go so far as marrying their own family members to maintain this perceived “purity” (Pure-blood, n.d.). Family members who marry Muggles or non-pure-bloods are often disowned, and witches and wizards who aren’t pure-blood are seen as inferior.
Overall, many pure-blood witches and wizards have prejudicial attitudes towards those who aren’t of their status.

Half-blood
Half-blood status refers to witches and wizards who have Muggle or Muggle-born parents or grandparents. Half-bloods are much more common than pure-bloods (Half-blood, n.d.). The term half-blood is a bit misleading, however, it refers to anyone with mixed blood status, not exactly half-and-half. Therefore, with this wide criterion a large majority of witches and wizards fall under this blood status (Half-blood, n.d.).
Despite the prejudicial attitudes some witches and wizards have towards half-bloods, half-bloods are seen as superior to Muggle-borns or Squibs in those who have prejudicial attitudes based on blood status (Half-blood, n.d.).
Some half-bloods, such as Voldemort and Severus Snape, persecuted or were prejudiced against other half-bloods, most likely because they were ashamed of their own half-blood status (Half-blood, n.d.).

Muggle-born
Muggle-born witches and wizards are those who were born of two Muggle parents. Their Muggle-born status does not in any way make them less talented magically; in fact, many of them are seen as some of the brightest witches and wizards of their time (Muggle-born, n.d.).
The origin of Muggle-born witches and wizards is thought to be that they are descended from Squibs who married a Muggle and the magical ancestry was forgotten about for many generations and resurfaces randomly (Muggle-born, n.d.).
Muggle-borns are sometimes referred to as “Mudblood” because of their (lack of) blood status (Muggle-born, n.d.). This is seen as a derogatory term and is not endorsed in any manner by the Department of Ancestral Research. They are often discriminated against, even though this prejudice is unfounded and is a result of ignorance in many cases.

Squib
Squibs are people who have magical parents, but no magical abilities themselves. They are quite rare and are often looked down upon by some magical folk, particularly pure-bloods (Squib, n.d.). It is said that if a child does not show any signs of having magical abilities before age seven they might be a Squib (or they might be a late bloomer) (Squib, n.d.).
Squibs are distinguishable from Muggles by having some knowledge about the magical world. They are similar, however, in the fact that they usually lead similar lives; Squibs often marry Muggles and lead a Muggle life as it is painful for them to see magic all around but not be able to perform it themselves (Squib, n.d.).

Half-breed
Half-breed is a term used to describe magical humans with one non-human parent. Being a half-breed is generally looked down upon, but they are able to use magic just like the rest of us (Half-breed, n.d.). Many witches and wizards are prejudiced against non-human creatures, and thus are against half-breeds as well (Half-breed, n.d.).
Different types of half-breeds include half-giant, half-goblin, half-veela, half-vampire, and possibly other, unknown types (Half-breed, n.d.).
