As an ex-scientist I wasn't astonished that I (mousy haired with some bottle blonde for good measure) and my equally mousey husband produced a red haired baby, but Not-naturally-thrifty Husband has certainly found it a) surprising, b) counterintuitive and c) the cause of endless 'so, who's the father?' wisecracks. There's a great, accessible explanation in Glenn Murphy's book 'Why do fart's smell?', if you can bear to buy or even borrow a book of this title!
The exhibition has triggered some interesting comment in the Guardian - 'is Gingerism the last acceptable prejudice?' and an interview with Jenny Wicks on Spoonfed. In my wanderings around this subject I have also discovered a blog dedicated entirely to Gingerism. I haven't delved too deep - perhaps I don't want to hear the horrors of prejudice life could hold in store for my Ginger boy. I'd rather hold on to the reassuring words of his splendidly ginger uncle, who reports having suffered no more than the next slightly shy school boy.
