  1. Harry Potter and theRecessive Allele How Are Wizards Made?

  2. How Are Wizards Made? • Being a wizard or a muggleis all decided by genetics • All humans including wizards receive one allele from each parent

  3. How Are Wizards Made? The allele for wizarding ability is: w • Wizards have • the alleles • ( w w)

  4. How Are Wizards Made? • The allele for Mugglenessis W • Muggleshave the alleles Wwor WW Ww – heterozygous dominant WW – homozygous dominant • Wis dominant to w so you can only be a wizard if you have no W allele

  5. The Malfoys NarcissaMalfoy (w w) Lucius Malfoy (w w) Draco Malfoy (w w ) W The Malfoys are a ‘pure blood’ family All their ancestors are wizards so they must have the alleles (w w)

  6. The Potters James Potter (w w) Lily Potter (w w ) Harry Potter (WW) w w Both Harry’s parents had magical ability so they must both have been w w They passed these alleles on to Harry

  7. The Weasleys are pure blood wizards so they all have the alleles ( w w )

  8. Hermione is a powerful witch so she must be w w Both her parents are mugglesso they must be Wwso they can give her a (w) allele each Ww Ww w w

  9. Tom Riddle is a ‘half blood’. His mother was a witch (w w) and his father was a muggle His father must have had the alleles Wwso he could give him the other w allele Ww w w w w

  10. Filch is a ‘squib’ Both his parents are w w so he should be too because he can’t get an Wallele from either parent but he can’t do any magic This means he has a mutation so his wizarding powers don’t work or the man he thinks is his father is not truly his father. His natural father must be a muggle!

  11. What wizarding alleles would Ron and Hermione’s children have? Hermione (w w) Ron (w w) Children w ( w )

  12. Their children could only get the wallele from both parents so they would all be wizards w w w w w w

  13. What wizarding alleles would Ginny and Dudley’s children haveIf Dudley is Ww? Dudley Ww Ginny w w Wwor ww

  14. Half of their children would be likely to get the w allele from both parents so they would be wizards The other half would be likely to get an M allele from Dudley and would be muggles w w w W w w W w

  15. Their children would get the w allele from Ginny and the Wallele from Dudley so they would all be muggles w W w W w w W W

  16. What wizarding alleles would you expect Hermione’s brothers and sisters to have?

  17. The Granger’s children have a one in four chance of getting w alleles from both parents and having magical ability They also have a one in four chance of getting Walleles from both parents and being a muggle They could also get only one w from their mother or father and still be a muggle w w w W W W w W
