Not to mention, if it were actually a Y-linked gene, then there would be no female mutants at all. So Pyro is probably just trying to rile up the parents 
If the Y-linked gene can only pass to sons, then how come women have their father’s eyes or noses or other features? Pyos os not riling up the parents, IMO. He only corrects the misconceptions that Bobby’s mother has.
Not necessarily. The gene for baldness is inherited from the mother, but mostly only effects men.
Women can have their father’s features because not all genes are sex-linked. If the mutant allele that gives you some specific trait (whether it be a big nose or a superpower) is on a non-sexual chromosome (an “autosome”) then it has a fifty-fifty chance of being passed on to any offspring, regardless of sex. It might not necessarily be expressed, but it has a fifty-fifty chance of being passed on.
The sex chromosomes are different, though, because women have two X chromosomes whereas men have an X and a Y. If you’re a woman, you’ve gotten an X chromosome from both of your parents. If you’re a man, though, you have to have gotten your X from your mom and your Y from your dad, because your mom doesn’t have a Y to give you.
This means that men can inherit X-linked traits from their maternal grandfathers, but not their paternal grandfathers. (You can also inherit X-linked traits from your maternal grandmother - 50% chance of either). So, if your mom’s dad had an X-linked gene that increases the probability he goes bald, you might get it - but if your dad’s dad had that gene, you have no way of getting it from him. Your Y chromosome, on the other hand, has been passed directly from father to son, and so has no way of affecting your female children.
Hope that helps - I feel like I’m just making things more confusing. If we want to pursue this further, let’s open up a general questions thread instead of continuing to take this one off course.
Lets do that. You start, and I will reply. But let me just add here, in school i learnt that the Y chromosome was highly unstable, and susseptible to mutation easily. that would make it a prime candidate for the evolution of the X Men
Ummm…isn’t that because the baldness gene is carried on the X-chromosome ?
Or was I whooshed ?
You know, considering that in the X-Man universe, there’s a gene for shooting laser beams out of your eyes, I think we may be over-analyzing the subject a tad. Clearly, genetics in the X-verse works entirely differently than genetics in our universe.
[really geeky nitpick] They aren’t lasers, they’re concussive beams that Cyclops’ eyes are somehow a portal to from some alternate dimension to ours. [/rgn]
Well, that’s much more logical! 
Maybe it was like this in the comics too (I’ve never read them) but I saw an interview with the director, and he said that in X-Men 1, they were trying to subliminally push the idea that the difference between Professor X and Magneto was the difference between X’s and O’s, so there are X’s and O’s ALL over the movie.
A war between kisses and hugs? Hershey’s may have something to say about that.
No, he absorbs cosmic energy and redirects it out his eyes! 
He does absorb cosmic energy but he doesn’t redirect it. It’s instead used to open the dimensional portals that are his eyes.

There’s a fascinating book called Science of the X-Men that attempts to explain each of the X-Men’s powers through science that is familiar to us. It’s pretty interesting how they explained telekensis. I don’t remember anything else other than I liked it, so you’ll have to read it yourself.
Just wait for the next retcon.
Xavier? Evil? Granted I’ve heard that they re going to recycle The Only Shitty Actor From Smallille as the next Prof X: Michael [del]Bloseraum [/del] Rosenbaum. Given that you can’t look him in the face and not see “your fist goes here” , and because that one-trick-pony can only act as a “shifty eyed sonofabitch” , you might doubt Professor X.
(I know I would)
Still, I don’t think the character was written with all Ex-Lex’s personal characer flaws in mind.
There are no bad parts. Just bad actors. (who keep getting cast like they are blackmailing studio heads with 8x10 Glossies of them in bed with Sheep.)
