(#12) Broad Lips
As with long eyelashes, many people seem to want a set of full, luscious lips. Lucky for them, broad lips are in fact dominant. Certain groups - those from hot climates - display this trait more commonly than others.
Thin lips and small nostrils help the body retain heat, which makes them genetically advantageous in cold climates.

(#8) Left Thumb Crossing
Put your hands together like you're praying. Of, if you'd prefer, clasp them together, fingers intertwined. Either will do. Now, which thumb is on top? If it's the left, you're displaying the dominant gene, and you're in the majority.
Studies have found that well over half the global population exhibits this trait, a random accident of genetics.

(#6) Long Eyelashes
Long lashes sure are lovely. They're also a dominant trait. Studies show that in many races and ethnicities, including Caucasian and Japanese, long eyelashes are definitely the majority.

(#1) Right-Handedness
Everyone knows being right handed is kind of the norm. If you doubt that, think about how hard it was to get left-handed scissors in kindergarten. A whopping 70 to 90% of people are right handed, all because right-handedness is a seriously dominant gene. High five, righties!

(#9) Left Arm Folded Over Right
Just as with fingers, the manner in which you cross your arms depends on your genes. In this case, the left arm folding over the right is dominant; more than half of individuals studied displayed left-over-right arm folding.

(#7) Broad Eyebrows
Getting pencil-thin eyebrows may be an enviable beauty feat for some, and that's mainly because thin, fine eyebrows are in the minority. Why's that? Well, as it turns out, thick eyebrows are a dominant trait.
Thankfully for our species, the unibrow is not a dominant trait.

About This Tool
Dominant genes refer to genes that can show traits in a pair of heterozygotes controlled by genes for relative traits or genes that have a decisive effect on the traits. On the contrary, if there is no trait, it is a recessive gene. Biology analyzes dominant genes have a variety of reasons, dominant mutation can induce a function in the cell, this function is either very beneficial or very harmful.
Common dominant genes include the color of eyes and hair. However, dominant genes may also carry genetic diseases. The random tool lists 14 common dominant genes in humans that you can find in your own body.
