While we're on the subject of hybrids, there is something that has always
puzzled me. If man hybridizes species A and B, the f1 generation is 50%A and
50%B. If the two populations exist closely enough in nature to form hybrids,
the original f1 generation would have probably been interfertile with A & B
and would further hybridize with A, for example, to form new hybrids, e.g.,
75%A and 25%B. Eventually we get a swarm of hybrids with variable
contributions of parents A and B. How do we designate the relationship between such
hybrids and the man made one of 50%A and 50%B and express the fact that they may
have the same parentage but variable contributions from each parent?

Bert,
I think the problem is much more complex. If you cross species A with
species B you get a hybrid which will be
intermediary, but not necessarily 50/50 ... remember Mendel's laws ...
Maybe our Prof. of Genetics cares to comment on this further.

Guido
