Why do i look the i way  look? 

*Everything you see in the mirror- from your height to yourhair color to the dimple(or lack there of) on your chin---is written into nearly every cell of proteins found in every cell of your DNA, Spiraling chains of proteins found in every cell in your body. think of DNA as your body instruction manual. It tells your cell how to grow into organs, hair, teeth,fingernails, your tounge andevery single other part of your body. Stretches of DNA (called genes) are like page in that instruction manual. Genes control what you will look like, plus less obvious traits such as whether you have perfect vision or the ability to curl your tounge.

2.Where did i get my genes?

while you admire your good looks in the mirror, don't forget to thank your parents. Genes come in pairs: one from Mom and the other from Dad. It's the combination of genes that bring about---or "express"---various physical traits(in a process called heredity). Some genes are more influntial on your appearance than other. The genes for dark hair are dominant over the genes for red and blond hair, making dark hair more common.

3. Do animal have DNA?

yes, all of them do, And not just animals. Every living thing on Earth---including single- celled bacteria, tree, plants----has DNA in its cells. you might expect to share many genes with a chimpanzee or bonobo, our closest living relatives, but did you know you also share genes with that banana the chimp is chomping 

4. Why do some kids look less like their parents than other kids do?

 You can't always guess a child's appearance just by looking at his or her parents . The study of genes called genetics is achieving breakthrough all the time, but much about heredity remains mysterious .combination of genes can effect  other genes leading to unpredictable charcteristics or feature that lurk in the genetics background for several generations. Our genes are also riddled with so called junk DNA that doesn't seem to express itself in any noticable way . Environmental and diet also play a large role in shapping a person's weight ,skin tone and other physical characteristics.

5. How similar AM I GENETICALLY TO.....

...A CHIMPANZEE ? 96--99%

humans and chimps spilt from a common ancestor between 13 to 6 million ago.

...A FRUIT FLY ? 60%

consider tis the next time you swat that itty -bitty bug buzzing arund your cantaloupe;You and that fly related! IN FACT SCIENTISTS ARE STUDYING FRUIT FLIES FOR CLUES TO BEATING CANCER.

...MY PET DOGS ? 82%

dogs  might be man's best freind ,"but read on for the shocking truth.

... MY PET CATS ? 90%

It turns out humans share more genes with felines than with fido.

... A BANANA ?  50%

No, this doesn't mean you're half banana. All life form on earth share fundamental feature and function at the celluler level . Sharing half our genes with banana just shows that we evolved from a common ancestor more than a billion year ago
