DNA Testing

DNA Testing was created in the 1980s, DNA testing began with the development of DNA fingerprinting by Dr. Alec Jeffreys, which allowed for the identification and comparison of individual DNA profiles, significantly impacting forensic science and paternity testing. The restriction fragment length polymorphism (RFLP) technique was introduced during this time, marking the first genetic test using DNA. Additionally, the first notable instance of DNA testing for genetic linkage analysis occurred in the U.S. in the mid-1980s, laying the groundwork for modern DNA testing practices. You spit in a tube, send it to a lab, and six weeks later your results come back saying you're 25% Nigerian, 13% Scottish, 7% Indigenous American, and the rest… a mystery soup. You feel excited. Maybe confused. Maybe even validated. But hold on. That DNA test might help you find your relatives, but it's not your cultural passport and it's certainly not the final word on who you are. Analogy 1: DNA for Relatives = GPS Coordinates. DNA for Ethnicity = Weather Forecast When you use a DNA test to find relatives, you're using exact coordinates of measurable genetic markers passed from one generation to the next, like a GPS signal. When you use DNA to predict your ethnicity, it's more like forecasting the weather. There's probability, pattern recognition, and a lot of assumptions about what "Scottish DNA" or " American Indian DNA" even looks like.

DNA Testing for Family: Think of your DNA like a chain of puzzle pieces. You inherit 50% from each parent, 25% from each grandparent, and so on. These patterns follow predictable rules — and science has mastered the math. Full siblings share ~50% DNA. First cousins: ~12.5%. A paternity test? Over 99.99% accurate. Companies like 23andMe or AncestryDNA can scan your genome and match you with people who share long identical segments. Those segments don’t lie.🔍 Example: If you and someone else share 3,500 cM (centiMorgans), the science says you’re parent/child or full siblings. That’s not guesswork, it's biology. 🌍 DNA for Ethnicity: Why It Fails Now switch gears. You ask: “Where am I from?” The problem? That question is social, historical, and often political, not purely biological.

Test

Short for Testosterone, is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.

Yo Gianni getting mad swole, he must be on that test

HISTORY PRE-TEST

When life comes to a halt and asks you one question...What do you know about history? The British are coming, Obviously there was the first and the fifth president, Johnny Depp has several islands, some painter guy was gay, A.D. means after death, B.C. means before Christ, and A.C.D.C. I still have no idea what that means, my previous history teacher should have been fired for cussing, Hawaiians believed in spirits, destiny child broke up, and I love that documentary with that one chocolate factory and that kid ummm yeah Charlie.

O MA GOD IT'S THE HISTORY PRE-TEST. MY COMEDIC TALENT IS AT USE BECAUSE THIS TEST HAS NO AFFECT ON MY GRADE.
TEACHER: HON I HOPE YOU TAKE THIS HISTORY PRE-TEST MORE SERIOUSLY TOWARDS FINALS, BUT FOR NOW MAKE ME LAUGH.
WHO IS THE BEST HISTORY TEACHER IN THE WORLD MRS. G
