Don't let the latest genetic research get your mom jeans in a knot: you might not have a natural drive to be a mom.

Apparently, some women’s desire to procreate is as genetically programmed as their green eyes or deeply carved dimples. I guess the rest of the moms are just faking it.

A genetic predisposition is the best researchers could come up with for the fact that many women in wealthy nations are choosing not to leave their legacies in the form of little packets of their genetic information, also known as children. Instead, these modern women want their legacy to be in the form of career, fame and fortune (narcissistic hussies!).

But don’t worry. Those women lacking a “mom gene” won’t be around for long. Since women in developed countries are now in control of their fertility, those who don’t care to become mothers, or don’t care to have many children, will breed themselves – actually, not breed themselves – into extinction.

Who will be left? The offspring of “mom gene” positive women. They will pass that baby-hungry way of theirs along to the next generation, who will pass it along to the next, and so on. Never giving less to motherhood than career, they'll raise the best darn kids ever.

What about those lacking the gene? Well, they’ll just sit around bitching about family-friendly airline pre-boarding policies, and how Judy’s taking another afternoon off to go watch a soccer game.

The researchers go further and posit that the population declines of developed countries could be stopped and possibly reversed. Fill up places like Canada, Italy, Japan and Germany with mom-gene carriers and you’ve got nursery schools outnumbering bars!

If there is such a mom gene, I think I might have it. My husband does not (hey, wait, what about the dads?). So I leave the mom-gene-negative cleansing to two my girls. But truly, I fear a world filled with nothing but devoted PTA presidents who, left unchecked, would have no one to guilt-trip, hold nightly meetings and bring back the mom jean on large scale.
