Oh, technically, biologically, of course, we were probably cross-fertile, but....

On the other hand all walnut, pecan, and hickory species are self-fertile and cross-fertile, but may be self-unfruitful because of dichogamy, because they may shed their pollen either before or after the stigmas of the pistillate flowers are receptive to it.

But the enthusiasm with which this applied result of Mendel's Law was at first hailed by biologists has gradually subsided; for it has been found that though these new forms will breed true under certain conditions, they are nevertheless cross-fertile with the original forms, and thus the circle can be completed back again by a return to the parent form, from which the new "species" can again be produced at will with the same mathematical exactness as before.
