x-chromosome

[Alejandra Goicoechea]

Hi,Being a woman, if I find a relative that shares some X-Chromosome segments with me, he/she is from my maternal side? or maybe from my paternal side too? Thanks for your help!

You have two X chromosomes as a women, one from your mother and one from your father, so relatives that share X chromosome segments with you could be from either side. 

Males have one X chromosome from their mother and one Y chromosome from their father. 

So if you have a male relative with X chromosome overlap, they will be related to you from their mothers side
