A double crown is a characteristic similar to your hair color or your eye shape. It’s linked to your genetics, and it doesn’t definitively indicate more about you. There may be certain genetic characteristics that people with a double whorl are more likely to have, but science hasn’t established these links as definitive.
What causes double crowns in hair?

The study concluded that a single gene controls hair-whorl orientation, clockwise as a dominant trait; that an individual's sex does not influence hair-whorl orientation; and that hair-whorl orientation is not linked to eye color.
What is double crown hair?
A typical hair crown is a patch of hair growing in clockwise motion around a visible center point on the scalp.

Is left handed one gene apart from right handed?
However, Klar's research methodology in this and other studies has been questioned. Another result concerning handedness of the progeny of discordant monozygotic twins suggests that left handed people are one gene apart from right handed people.
Dimples
There's nothing cuter than a dimple or two on a baby. Little indents that seem to light up a baby's face when they smile, are in truth simply genetic defects caused by shortened facial muscles. Whilst I don't think anyone would refer to dimples as defects, there are those who believe they are more than just a muscle trait.
Birthmarks
Birthmarks come in all shapes and sizes and range from lighter coloured "stork bites" that are the result of clusters of pigment cells, and bright red "strawberry marks" often caused by abnormal blood vessels in or under the skin.
Natal teeth
I had to include natal teeth as they are such a rarity. While it may appear strange to see your baby born with teeth, it is actually quite normal. Every baby is born with teeth, although in most cases they are hidden under the gums.

Does Sarah have a double hair whorl?
My wife & I took our daughter Sarah to see a geneticist and neurologist a few months back (she has a delay in motor skills but not speech or cognitive abilities, if that's relevant) and the geneticist noticed that Sarah has a double hair whorl (i.e., her hair grows out of her head in two circular patterns as opposed to the usual one--also one pattern goes clockwise and the other counter-clockwise).#N#The geneticist suggested that this was associated with higher rates of developmental delays, but from what I've read that seems to be far from accepted and in fact there are some people who suggest that this pattern is associated with gifted children.#N#What does appear to be more widely accepted is that this pattern is associated with handedness and that with this particular pattern my daughter has a 50% chance of being left-handed (much higher than the general population).#N#I'm curious what the reason might be for associating hair patterns with handedness or cognitive development and whether any of you who know more about genetics might have more information on the subject.
