Genetic Science

Genetics is the study of cellular science. It furthers our understanding of how DNA and the genetic make-up of species and can lead to cures for diseases and shape our future.

Before the widespread use of DNA, establishing the paternity of a child was a tricky business. Ever heard of the oscillophore?

After scientists announced the first draft of the human genome, people began to wonder how our new understanding of DNA would change life. Several research institutes stated the accomplishment would revolutionize science and modern medicine -- but how, exactly?

What's more fun than looking at pictures of DNA and celebrities? Check out Dolly, dimples and dominant and recessive traits in this fun gallery charting how genetics play out in humans (and a few animals).


How can children from the same parents look so different? I mean, why don't all kids from the same parents look exactly alike, since the parents just have one set of chromosomes each and they don't change?

A Punnett square helps predict the possible ways an organism will express certain genetic traits, such as purple flowers or blue eyes.

CRISPR is the genius behind innovations that seemed impossible a decade ago. Could you grow tomatoes with the kick of hot sauce or ferment wine that doesn't cause a hangover? That's just two of the things scientists are looking into.

If your eyes are the windows to your soul, then your face might just be the window to your DNA. An examination of your face shape could determine if you suffer from a genetic disorder.

Ever since I took biology in high school I have wondered -- why do humans (and plants and animals) have two of every gene, and why is one "dominant" and the other "recessive"? How does my body know which one is dominant? How does it pick between the

The physical you is a result of your DNA, and your DNA is part of the human gene pool. Find out what the "gene pool" really is and what happens when it shrinks.

Given the choice, would you rather have been born with a different eye color, hair color or skin tone? Of course, you didn't have these options, but could you have them for your own children?

The CBS drama "CSI: Crime Scene Investigation" routinely uses cutting-edge technology to solve crimes, including collecting and analyzing DNA evidence. But catching a criminal using DNA evidence is not quite as easy as "CSI" makes it seem.

How would you like to be the person responsible for changing science and Western civilization? With the "Origin of Species," Charles Darwin did. How did this English gent become the reluctant ambassador of evolution?

More than 50 years have passed since Watson and Crick untangled the structure of DNA and five years have elapsed since scientists finished sequencing the entire human genome. What have we figured out about our genetic material?

That bowling ball of white meat in your oven is a far cry from its wild ancestors. How did a single breed of top-heavy, dim-witted birds come to dominate the turkey market?

Much like Noah, researchers are stockpiling the genes of Earth's living creatures, loading them into state-of-the art facilities and freezing them. Are scientists saving them for a rainy day?

Ever hear that urban legend about waking up without your kidney? Would organ thieves have to find a new line of work if cloned organs became a reality?

Hereditary illnesses are passed down from parents to their children like gene traits, and children might inherit a disease even though their parents never suffered from its symptoms. Learn about hereditary illnesses.

Doctors always want your blood, but one day, a health care professional may ask you to open up and say, "Ptooey!" Why? Your spit holds a mother lode of biological information.

Can humans live forever? No, but thanks to the discovery of the Hayflick limit, we know that cells can conceivably divide forever without dying.

The Atacama skeleton has sparked intense controversy and, based on its appearance, speculation of alien origin since its discovery in 2003. But what is the real story behind this little skeleton?

You probably feel like you have very little in common with that banana lying on your kitchen counter. But science says you do! So, how is this possible? And is that stat accurate? We talk to the scientist who did the research.
