Many babies start out with lighter eye colors that can change after a while, as you'll see explained later, but it could also be in their genes...

▲

Even if you have brown eyes, you could be carrying a recessive gene like blue or green eyes behind it. In Drake's case, his mother's light-eye gene may have just been waiting for the right match to appear, along with her blonde-hair gene.

▲Many celebrities seem to have these beautiful light eyes, which actually gives a false impression of how common the trait is.

▲Jennifer Aniston also shares this trait, which, even though regarded as beautiful, is actually a genetic mutation.

▲People with green or blue eyes actually comprise a fairly small percentage of the world's population.

▲It is estimated that only around 2% of the world population has green eyes.

▲Most of the population with light-colored eyes have European roots.

▲The UK and Ireland are examples of where most of green-eyed people are concentrated.

▲But why are some people born with blue or green eyes?

▲Chromosomes 1, 15, and 19 are responsible for transmitting the mother and father's genes to the baby.

▲If there is a brown-eye gene in that mix, the baby will be born with brown eyes because that is the dominant gene—this is what happens to most of the population in the world.

▲But if both genes that are passed on to the baby are recessive, then it will be born with blue or green eyes.

▲The amount of melanin is what defines the eyes' exact color.

▲The blue represents a total absence of melanin.

▲As for green eyes, a certain amount of melanin can be found.

▲

Melanin has a very important function: to protect eyes from sunlight.

▲That's why light-colored eyes are more sensitive to solar rays.

▲

People with green or blue eyes need to be doubly careful when it comes to preventing certain eye problems such as cataracts.

▲In 2008, a study revealed surprising information about blue eyes.

▲Danish researcher Hans Eiberg said that everyone who has blue eyes is somehow related.

▲According to the research, blue eyes appeared around 7,000 years ago thanks to a genetic mutation.

▲According to the study, which happened near the Dead Sea region, the mutation has since then been passed on through generations.

▲But according to a 2017 CNN article, all human eyes are brown!

▲According to the study, some people just appear to have light-colored eyes because of their low melanin content.

▲Have you noticed what happens to babies sometimes?

▲Some babies are born with blue eyes but the color ends up changing to brown with time.

▲

The explanation for this phenomenon may be contained in a study published by Live Science in 2011.

▲According to researchers, the child's development includes a rise in melanin levels, which ends up changing their eye color.

▲

You'll never look at someone with blue or green eyes the same way!

In 2020, Drake posted the first photos of his headline-making son Adonis, and besides the incredibly beautiful caption he wrote, people are taken aback by the sight of Adonis—more specifically, the bright blue eyes that go with his curly blond hair. As both Drake and Adonis’ mother, Sophie Brussaux, have brown eyes, people are a little confused. Can brown-eyed parents have blue-eyed kids?
