Genetics and corpus calusum

Don't know, but I doubt it.  I'd think the differences, if really
reliable, would be due to intrauterine influences, such as, say the kid's
testosterone.  I also think Y is too small to have much on it.  Not that
that means a lot.

That said, about 1:20,000 males are XX with the TDF gene havinf hopped to
an homologous spot on the X chromosome.  They are sterile, as some sperm
stuff is on the Y and only on the Y, but nonetheless that population is
there.  I don't know if anyone has looked at the callosum.   They are,
though, really male, since all the tissues responded to the testicles that
the TDF started.

       Faith and fantasy from fact,
       The illusory from the true,
       And starve upon the residue.
