Mini-Maleness

As if men don’t have enough of women making jokes about the way we act with our buddies, have you ever seen how the male Y chromosome compares to the female’s X chromosome? Here … take a gander:

It’s well known in genetic circles that the Y chromosome has continued to diminish in size because feminine characteristics have always been necessary in women to ensure preservation of the species. After all, men ARE attracted to females with womanly characteristics, right?

So DNA with male characteristics has always been protected, and are not swapped with female DNA when ovum fertilization takes place. It’s kind of like the Y chromosome erected an impenetrable castle wall around its male DNA to protect it. The female X chromosome does the same thing, but protects fewer DNA.

(Females reading this are undoubtedly smiling, concluding that at last they have proof of their influence over us males.)

Much of the male’s DNA became dispensable, so they slowly were shed. Consequently, male Y chromosomes have only 27 genes in the “no-swap” castle, while female X chromosomes have 790. (Those darned, gene-hoarding female X chromosomes!)

The thing is, the Y chromosomes have continued to shrink. And every man knows that shrinkage is not a good thing ... I'm just saying ...
