Today’s Nature has an interesting letter suggesting a way to introduce genetics to children–even kids as young as 5, they suggest. Harness pop culture–specifically Harry Potter–in order to introduce basic concepts in genetics.
A portion of the correspondence reads:
Most children are familiar with J. K. Rowling’s stories about the young wizard Harry Potter…. They are set in a world like our own, but populated by a minority of people with supernatural powers (wizards and witches) and a majority of people without (muggles).
Wizards or witches can be of any race, and may be the offspring of a wizard and a witch, the offspring of two muggles (‘muggle-born’), or of mixed ancestry (‘half-blood’).
This suggests that wizarding ability is inherited in a mendelian fashion, with the wizard allele (W) being recessive to the muggle allele (M). According to this hypothesis, all wizards and witches therefore have two copies of the wizard allele (WW). Harry’s friends Ron Weasley and Neville Longbottom and his arch-enemy Draco Malfoy are ‘pure-blood’ wizards: WW with WW ancestors for generations back. Harry’s friend Hermione is a powerful muggle-born witch (WW with WM parents). Their classmate Seamus is a half-blood wizard, the son of a witch and a muggle (WW with one WW and one WM parent). Harry (WW with WW parents) is not considered a pure-blood, as his mother was muggle-born.
Interesting idea. You teachers out there, any other good suggestions?
