This is how Satan's emissaries do evangelism.

Wow, I'm surprised he gave a terrible answer to the first question. I think the guy left not only not very much enlightened but quite confused.

Anyway, congrats to Dr. Benkovik on his award and his outstanding career.

I'd have asked him at what point in time my gene's came into existence. Then he'd have had to explain that the half I got from my mother were actually created while she was a developing fetus, but that the ones I got from my father were just a few weeks older than the point in time when I was conceived. That a man's genes are slightly older on average than a woman's because the Y chromosome is inherited intact, and that the mitochondrial DNA comes only maternally and is the oldest of all, etc.

[RyuDarragh]

Your genes are from your mom and dad. Half hers, half his. They play a game called "gene shuffling", too. And gene duplication and gene deletion. A males Y chromosome got that way due to gene deletion. Some diseases happen when the Y chromosome is stuffed with DNA from the X chromosome.

[ananiasacts]

I was under the impression that the Y chromosome did not take part in homologous chromosome crossing over. You get that from you dad, intact.

[RyuDarragh]

The identical parts do. The missing parts don't (obviously). There are parts that don't participate (nearly 95% in humans), right enough, but errors happen. Androgen Insensitivity can be caused by this. You get an XY female. And the opposite, an XX male (the SRY gene gets swapped onto an X chromosome). The Y chromosome can use a sort of self-autosomal crossover with palindromic versions of the genes (same, but backwards).

Pre-selected questions im sure.

[skarefamena]

Not a chance. If they were preselected, he would have actually had good answers.

LAST! YES

[JW93HB07]

i thought this was very good, even though i don't particularly enjoy biology, though it was very informative and it shows that everyone is effected by science. its just about time more people woke up to it

Msg me your email and I'll send you the article.

[farvision]

just give a link. I don't give my email out here.

Bigflexi, don't 'Dis' your daddy. I't's not cool.

You're just another cyberbitch afraid to show your face, I laugh at you for days.
