Can a guy get either x from their mother

Question

Can a guy get either x from their mother xx or both x combined into one x then passed to their son

Answer 1

Yes, a guy can get either of mother's X chromosome, unless:

 

 1. there is a mutation in one of the  X-chromosome that makes that particular X-chromosome carrying ovum incapable of fertilization or arrests the development.

 

2. there is an haploinsufficient region that arrests  development.

 

3. there is a lethal mutation in one of the  X-chromosome that does not support the survival of  that particular X-chromosome carrying zygote/embryo/fetus  in single dose.

 

 

Hope this helps as well.

 

 

 

Answer 2

Hello.  A Male human has one X chromosome and one Y chromosome (XY).  The X chromosome comes from the mother, and the Y chromosome comes from the father.  Females have two X chromosomes (XX). One X chromosome comes from the mother, and the other X chromosome comes from the father. 

 

I hope this answers your question.  If I can help you with any other questions, let me know.
