The magic gene is a portion of human DNA that determines whether a person will have magical abilities. Those people born with the gene active are witches and wizards, while those who are not are Muggles or Squibs.

The magic gene is dominant[1], and any child born to a wizarding family will have some degree of magical ability, or at least magical awareness. Squibs , while unable to use magic, are still able to function within the wizarding world to a limited degree. The descendants of squibs who instead integrate into the muggle world and marry will usually be muggles, although the magic gene occasionally resurfaces in later generations and produces a Muggle-born witch or wizard[2].

Behind the scenes

  • J.K. Rowling stated that she had considered having Dudley Dursley have a magical child in the epilogue, and see them off to Hogwarts at Platform 9 & 3/4 at the same time as Harry and his family. She decided against this, however, stating that any latent wizarding genes would never survive contact with Uncle Vernon's DNA.[3]
  • According to J.K. Rowling, nobody knows where magic comes from.[4]
  • Despite the magic gene being dominant, that doesn't explain Squibs or Muggle-borns, or how muggle borns manifest their powers the same way as Half-bloods or Pure-bloods. It is therefore possible that magic is controlled by more than one gene or is only partially dominant.
