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.

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).

With headlines about cloned meat entering our grocery stores and all that talk about Dolly the sheep, you might be surprised to learn that many animals aren't so easy to clone.

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.

Whole genome sequencing can analyze a baby's DNA and search for mutations that may cause health issues now or later in life. But how prepared are we for this knowledge and should it be used on all babies?

The 2003 announcement that scientists had completed the first human genome came with an 8 percent gap. Now that gap has been filled and the first end-to-end human genome has been published.

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.
