Not true. Hair colour is not determined by a single gene, so although a recessive "ginger" gene is quite influential it is still possible for two ginger parents to produce a non-ginger child. For greater detail see here:http://udel.edu/~mcdonald/mythredhair.htmlYou should go and thump the biology teacher. As any fule kno, ginger, like blue eyes, is a recessive gene. Two gingers will always produce a ginger child, but you can have two non-ginger parents and if they both have the ginger gene lurking in the background, they've got a 25% chance of a ginger child.
