Hey, prospective parents: Say you're smitten on having a girl? Make sure you have a good-looking partner.

There's a new trend surfacing in maternity wards, and it pretty much suggests that attractive parents tend to have little girls more often than their homelier counterparts.

Beautiful women and hunky men are more likely to have daughters than those who were less blessed in the looks department, according to a study published in the journal Reproductive Sciences and reported in the Daily Mail.

Dr. Satoshi Kanazawa of the London School of Economics analyzed data from a survey of 17,000 babies born in Britain in March 1958, and tracked them at various points in their lives, including at age 7, they were rated as attractive or unattractive by their teachers, and at 45, when they were asked to record the age and sex of their children.

Kanazawa found that while the children who were rated as attractive -- 84 percent of the sample -- were equally likely to have a son or a daughter as their first child, the unattractive children were more likely to have sons, the Daily Mail reports.

And it may also explain why many models have daughters who follow in their glamorous footsteps, such as Yasmin Le Bon, who is signed to the same modeling agency as her daughter, Amber, and Jerry Hall, whose daughters Elizabeth and Georgia Jagger have both taken to the catwalk, the Times of India reports.

Kanazawa tackled the same question in a 2007 book that covers all sorts of facets of human behavior, "Why Beautiful People Have More Daughters," which he co-wrote with Alan S. Miller.

Kanazawa writes in the book that attractiveness benefits women more than men when it comes to long-term dating and mating, MSNBC reports. Guys tend go for beautiful women when looking for something long-term, while women seek out good-looking guys for the short-term, but not necessarily for the long haul, when qualities including resources and status count for more, Kanazawa says.

"So physical attractiveness, while a universally positive quality, contributes even more to women's reproductive success than to men's," Kanazawa and Miller write in their book. "In an evolutionary psychologist's point of view, pretty parents pass along what will best benefit their progeny: good looks."
