Muggles' Guide to Harry Potter/Magic/Muggle-born
|Muggles' Guide to Harry Potter - Magic|
|Features||Born of two non-wizarding parents but has magical ability|
|First Appearance||Harry Potter and the Chamber of Secrets|
In Harry Potter and the Chamber of Secrets we are introduced to another name for those witches and wizards born of Muggle parentage - Mudbloods. This is an insult used only by purebloods who feel that Half-blood and Muggle-born witches and wizards are somehow inferior to purebloods.
Apparently it is not necessary to have magical ancestry to be able to do magic oneself; it seems that magical ability can spontaneously appear without known magical ancestry, and sometimes in only one child of a given union. Lily Evans' sister Petunia showed no sign of magical talent, though her son Dudley may have shown a hint of ability.
Through a process possibly akin to hybrid vigor, it seems that many of the most powerful wizards have some Muggle in their recent background.
