I think I took the same class. I barely payed any attention to the lectures and thought it would be easy. WRONG! First test score was a D and I had to work my ass off to overcome that and eventually get a solid B, which I was actually happy with.Yeah male pattern baldness is a sex chromosome deal (I did a paper on it for an intro biology class in college).
It's been awhile but the gist is it's all about the X chromosome. Since women have two X's it gets supported by the other, but since dudes are X-Y you've gotta hope the recessive gene isn't the X that your mom gives you cuz that's all she's got...X chromosomes.
Meaning if your dad gave you a Y, turned you into a dude...your X 100% came from your mom and most likely has the recessive MPB gene.
That's why they say look at the mother's father, that probably determines your hairline.
As a boring sidenote, that class was insanely difficult. It was filled with business douchebags like myself instead of legit students of biology and chemistry. The grading curve was literally 50%, meaning if you got half the test questions right you got an A.
For the final I decided to try to memorize all the previous test questions and noticed that most of them repeated, multiple times. The f#$king professor repeated questions knowing we were all idiots and would never notice. I ended up getting like an 80% on the final and laughed my ass off when we all gathered round the big board knowing I'd be in the #1 spot.
Sometimes it's just about the game.
If I recall, we talked about fruit flies a lot. That's about all I remember. lol
