But an enterprising geneticist wants to make things easy for everyone: She's giving the world a glimpse of how she thinks the royal spawn will look, months before the Duchess of Cambridge even goes into labor!
South African geneticist Suretha Erasmus has drawn on some nifty scientific know-how (not to mention some rockin' Photoshop skills) to composite an image of Will and Kate's child.
Per The Huffington Post, the esteemed scientist believes the royal heir could inherit Kate's brunette hair, given the predominance of dark genes.
She also posits that because William inherited many of Princess Diana's facial features, there's a strong likelihood that the child could resemble the late Princess of Wales.
Of course, in the service of covering all bases—not to mention satiating everyone's curiosity—Erasmus has come up with mock-up images of the couple's firstborn as a boy and a girl and as a toddler and a grown-up. Snazzy!
Kate was spotted earlier this week shopping at a London Topshop, where, naturally, she supposedly checked out some chic maternity wear.
