When you consider what Mendel accomplished and
when he accomplished it, he was indeed amazing.
I always tell my students that if a Nobel could
have been given posthumously, Darwin and Mendel
would be "sure bets."

I have not examined Mendel's extant notes and so
on first-hand, but it is my understanding from
reading a few biographies that other notes are
available and indicate that he worked with other
traits that DID fail the 3:1 ratio...he just
didn't publish on those. Why not? I guess that
is speculative.

In our litigious society perhaps he would be
brought up on Ethics charges...but when you
realize that the idea of genes, DNA, both male
and female contribution to genetics, cytogenetics,
diploidy, and so on were not even known...well
his work is just fantastic! That his work fell
on deaf ears in biology is no surprise as the
math-science connection had not been made yet.
I use this as an explanation for why math is
required of science majors...

The biographies indicate that Mendel was not
a very good teacher (at least not in the estimation
of his peers) and perhaps he wasn't reverent about
books in the library either.  Some of the books
in the library of the monastery have what are
considered to be Mendel's marginal notes. So
maybe Gregor wasn't the "angel" we sometimes
paint him to be...but he WAS a gifted scientist...
definitely WAY ahead of his time.
