Chromosome Assumptions

While I was growing up I made the assumption that a Y chromosome automatically made males capable of fixing plumbing, riding horses, hammering things, combustible engine experts, and sports nuts. I have since discovered that the Y chromosome apparently does not create these attributes!!!  I was shocked, on the other hand, my husband probably assumed that two X chromosomes would assure him of someone who could cook, keep house, and sew a button. We were both wrong...
