Is there soemthing in a Y than you can't get from an X?

You can't make an X from a Y, or a Y from an X. Unless you invoke some exotic/artificial stuff.
 
Is there soemthing in a Y that is not in an X?
Maybe we can't do it, but I believe it is theoretically possible.

yes, there is.

Unless you mean they're both made from A, G, T, and C...in which case I guess you could rearrange an X chromosome to make a Y. But they don't have the same genes.

reread my post above.

A Y chromosome is not an X chromosome with an arm chopped off.
 
not possible. aside from introducing a completely different Y to replace the X. which we also can't do, but is more feasible. Ychromosomes and X are extremely different. they code for vastly different proteins and contain different triggers, etc. if it were possible to make such drastic changes to a chromosome, then technology would have a better way, i.e. complete replacement.

Did you even read my post?

You can make a Y chromosome from an X chromosome like you can make an Enzo from an Abrams tank. Only if you melt it down and rebuild it from the basics.

Well, how far down do we have to go.
amino acids?
or is it siply a matter of removing certain sequnces?

I think all the Y sequences are there.

yep. X and Y is like apples and oranges. there are a few peices that are the same, but many more that are completely different. if you stripped it down to the most very basic components then maybe. but then it would probably be easier to make it from scratch.
just like it would be easier to make an enzo from scratch than to melt down an abrams to make one.

agreed, much easier to make from scratch whhen possible...but we are still mapping out genes and the human genome, not creating them....

Can anyone tell us the sequence missing from an X which is needed to make a y?

it's not like there is a single sequence difference. your talking about millions of codons. vastly different proteins are present in women than in men.

not like one is less than the other one. just different. you would have to replace many many individual parts. on the order of millions of different sequences.

You can easily get a Y from an X. All you have to do is chop off one of X's "legs", and you're left with a Y that looks like "y". See that? It's missing its right leg.

Before any wannabe scientists bash me, that was a joke.
