Explore the fascinating world of wizard genetics as seen in Harry Potter. In this intriguing analysis, we learn how wizarding abilities are passed down through generations via dominant and recessive genes. Discover how pure-blood families like the Malfoys and Potters inherit their traits, while half-bloods and squibs, like Filch, illustrate the complexities of magical lineage. With examples from the beloved series, we unravel what it means to be a wizard or a Muggle, addressing questions about the nature of magical heritage and the underlying genetics that define it.

  1. David Elliott

  2. Harry Potter and theRecessive Gene How Are Wizards Made?

  3. How wizard genetics works? • All humans including wizards receive one copy of each gene from each parent

  4. How wizard genetics works? ● Some genes can be dominant ●Some genes can be recessive

  5. How wizard genetics works? ● Some genes can be dominant ●Some genes can be recessive And we are going to learn about this from Harry Potter!

  6. The characters…………. Wizards and Witches

  7. The characters…………. Squibs

  8. And finally…………. Muggles!

  9. How Are Wizards Made? Being a wizard or a muggle is all decided by genetics

  10. Let’s look at some examples from Harry Potter

  11. Let’s look at some examples from Harry Potter First…………….Pure wizards are born from wizard families

  12. How Are Wizards Made? • The gene for wizarding ability is w • Wizards have two ww genes

  13. The Malfoys Narcissa Malfoy (ww) Lucius Malfoy (ww) Draco Malfoy () w w The Malfoys are a ‘pure blood’ family. From the past all their ancestors have been wizards so they must have the wizarding genes ww

  14. The Potters James Potter (ww) Lily Potter (ww) Harry Potter (WW) w w Both Harry’s parents had magical ability so they must both have been ww –like all wizards They passed these genes on to Harry

  15. The Weasleys are pure blood wizards so they all have the genes ww too

  16. A special thing about the wizarding gene • w (the gene to make a wizard) is recessive so you can only be a wizard if you have two w genes Remember, you get two copies of every gene

  17. What about Muggles? Muggles have the other kind of gene - DOMINANT

  18. How Are Muggles Made? • The gene for muggleness isM • Muggles have the genes Mw or MM

  19. How do you get wizards or witches from muggle families?

  20. Hermione is a powerful witch so she But, both her parents are muggles so they must be Mm so they can give her a w gene each Mw Mw ww

  21. More examples from Harry Potter Next…………….Half-bloods

  22. Tom Riddle is a ‘half blood’. His mother was a witch (ww) and his father was a muggle His father must have had the genes Mw so he could give him the other w gene Mw ww Mw

  23. More examples from Harry Potter Next…………….Muggles born in Wizard families

  24. FILCH Filch is a ‘squib’ Both his parents are wizards (ww) so he should be too because he can’t get an M gene from either parent but he can’t do any magic This means he has a MUTATION so his wizarding powers don’t work!

  25. FILCH In other words, his wizarding gene w has broken!

  26. Some questions for you

  27. What wizarding genes would Ron and Hermione’s children have?

  28. What wizarding genes would Ron and Hermione’s children have? The answer: Ron (ww) Hermione (ww) Children ( ) w w

  29. We all have dominant and recessive genes too

  30. Dominant and negative genes Dominant genes: Brown eye colour Negative genes: Blue eye colour

  31. Let’s take a look at you… Grab a partner…

  32. Final Question

  33. Is anyone here a Wizard?
