Biggest Half-bloods Harry Potter Plot Hole That Makes No Sense
How do muggle-borns get their magic in the Wizarding World?
While muggle-born wizards and witches are a common thing in the Harry Potter universe – think Hermione Granger and Lily Evans – Harry Potter fans are still confused about how the whole magic-discovery-thing works for them. The original books give hardly any answers to many questions fans might have about the muggle-born magic, leaving some serious plot holes open for discussion.
The first and main question every fan is bound to have after reading the very first Harry Potter book is where the muggle-born magic comes from. Does it just show up out of nowhere when a Muggle turns 11? Are there any conditions that must be met?
Well, this mystery has several theories explaining it. The Wizarding World webpage, for example, refers to muggle-borns as 'Magbobs', an affectionate name given by wizards back when magic was considered to just "bob up" out of nowhere in a muggle-born child.
However, another much more clever theory was in fact given by J.K. Rowling herself in a web chat back in 2007. Rowling explained that the source of the muggle-born magic is a special magic gene. It means every muggle-born wizard or witch has a magical ancestor somewhere on their family tree.
Harry Potter Wiki goes even further, explaining that ancestors of muggle-born wizards and witches are actually Squibs who had married Muggles at some point in the past. Such families lose not only magic but any knowledge about it, so when the magic gene resurfaces many generations later, it seems that the magic came out of the blue.
Some fans think that it is not one magic recessive gene, but a combination of several genetic factors that results in people becoming wizards. This theory gives a better explanation of how magic muggle-born siblings – Colin and Dennis Creevey, for example – are possible.
At last, the theory of multiple genetic factors gives us another very intriguing possibility. What if all wizards and witches come from Muggles? Some mysterious combination of genes once gave an unexpected result – a magic child was born from two Muggle parents. Eventually, this "accident" became more and more common and a large wizarding community was formed. Some of them preferred to forget about their muggle background and started calling themselves pure-bloods and hating all muggle-borns. Wow, we wish pure-blood elitists of the Wizarding World would learn about this fan theory.
