As a male my X chromosome comes from my mom and Y from my dad. This same Y chromosome comes from his dad and so on. Does this mean that I essentially have none of the genes or hereditary lineage of the women in his line?i would assume no, but since the Y chromosome I have came from his father and the X from someone on my mother's line I don't see what I could have from, say, my dad's mom.i sent this as a PM to joie but i'm pretty curious.

Your dad's Y chromosome is made up of his mom's X and his dad's Y. So essentially you're getting both your dad's parent's genes when you get his Y chromosome.That sounds right, but is it right? ]

yeah, your sex chromosomes mutate during your life so whenever you pass one of them along, it won't be an exact copy of what it was when you received it

i like where this thread is going
6/29/2009 11:38:36 AM
ummm, wat?
6/29/2009 11:38:37 AM
^4, but i would think my dad's Y is my grandfather's Y and my dad's X is only his mother's X. Only the dad has a Y to give and the mother an X. It would seem that i would have to have hereditary traits from all people involved but just thinking on levels of X and Y and DNA testing I am not sure how.

Meh, I was a math major. I took Biology one semester and that was it. Lemme know when you find out though, you've got me thinking!

the only point in time you have your dad's Y chromosome is at conception, as soon as the fertilized egg starts mitosis, it is then YOUR Y chromosome... although it may retain many of the same genes, many of your father's genes are not in play anymore

As a man, you have 22 other chromosomal pairs then an X and a Y. The other 22 chromosomes that came from your father could have come from your father's mother or any other females on your father's side.The Y chromosome can be used to trace male lineage and has been used in population studies, but don't forget that you have more than just the X and Y chromosomes.

Thanks. I knew there were 46 pair I just didn't know what information they contained and from where.

there are very few y-linked traits. in most everyday cellular function, the y chromosome merely acts as a placeholder for an x chromosome. in a womans body, one of the X chromosomes is randomly deactivated in each cell so there wont be an excess of X-chromosome gene products. so roughly half the cells in her body are expressing one x chromosome, and half are expressing the other. your extra X chromosome has already been deactivated due to incompleteness, so all of your cells are expressing the same X chromosome- the only one you has. X and Y chromosomes do not undergo recombination in meiosis, only X and X. so your Y chromosome is the one your dad has, while your X chromosome is a mix of the two your mom has.

The Y-Chromosome is also trash DNA.My feminist and aggressive female friends were more than happy to tell me this on a weekly basis.

^ Nice son.
6/29/2009 1:39:06 PM
The Y Chromosome basically says "grow testes" and that's it.
6/29/2009 1:40:35 PM
^^ Do you talk like that in real life? 1,000,000 points to you if you do.^ hahahaha[Edited on June 29, 2009 at 1:41 PM. Reason : .]
6/29/2009 1:41:01 PM
Naw, I don't speak like that in real life son.
6/29/2009 1:42:46 PM
Oh well. I admit, I do miss the all caps.
