Dowbrigade

American
Journal of Human Genetics explains
why the Dowbrigade always checks with Norma Yvonne always checks with
Norma Yvonne before leaving the house in the morning, to make sure we
aren’t committing a color-coded fashion faux pas…

It turns out there’s a perfectly good reason why men can’t see what
is so obvious to women: the many variations–some subtle, some bold–of
the color red.

Reuters reports that researchers from Arizona State University in Tempe have
determined there is a gene that allows us to see the color red, and that gene
comes in a high number of variations. Because the gene sits on the X chromosome–and
women have two X chromosomes and so two copies of this gene, compared with only
one for men–the gene aids women’s ability to perceive the red-orange color spectrum.
