How a ‘green’ gene made us green: How we learned to be blue
A gene can be a gene, and that’s why many people think of a green eye as a blue one.
But genetics is more than just a gene.
The human genome contains genes for more than 70 different traits, and many of those genes are shared between all people.
And if the same genes are passed down through generations, that gene could affect the way your eyes look.
That’s what genetic mapping and computer science can do for us.
This week, we look at how the genetic makeup of green eyes can affect our health, the genetics of a blue eye, and how to spot a genetic difference.
Genetics explains what makes us who we are The human genetic code is divided into five components: the genes that make up our DNA, which encode proteins and enzymes; the regulatory regions, or regions that control when certain genes can be expressed; and the instructions, or instructions that guide how genes function.
Genes play an essential role in everything from the structure of our cells to how we form our memories.
But genetic mapping isn’t just for genes.
It’s a tool that can help us understand what makes our bodies look, feel, and act like we want them to.
In the last few years, scientists have been studying the genetics and anatomy of human eyes, to learn more about how genes and other genetic components interact to make us human.
“It’s a very important piece of research,” says geneticist Christopher Wojcicki, an assistant professor of molecular genetics at the University of Washington.
“We need to understand how they interact to shape human health.”
