Spotty Sight
Ladies, cut your partner some slack if he can't seem to come up with a matching shirt and tie combo on his own: Around 1 in 10 men suffer from some degree of color blindness. Color blindness is a genetic characteristic, linked to the X chromosome, and as you may recall, men only have one X chromosome, while women have two. Luckily for the ladies, you need just one color-blind-free X chromosome to see color clearly, and as a result, women rarely (as in less than 1 percent) inherit the condition.
