More genetic misrepresentation

The Daily Mail strikes again, in today’s Herald story headlined “Gene explains why girls like sweet stuff more than boys”

The actual research did an experiment to look at differences in what snacks children chose. The difference they found was in fat consumption, not sugar, and, overall, girls actually ate a bit less than boys, not more. Here’s the graph from the paper

The potentially interesting finding was that the difference between kids with two versions of the gene was larger for girls than boys, suggesting that the gene may act differently in boys and girls.
