That was not the point I was making.

I appreciate and undersatdn what you say about
sex determination. This is not in question

My point was that the man (father) is merely the
keeper of the 'X' chromosome which you seem to
admit he gets from his mother. There for a
daughter (female) gets one from her mother and
the 'X' that has come from her father was her
paternal GRANDmother's.

That is my point.
