Font breeding is much like animal breeding, where stallion and mare, or bull and cow, or boar and sow are carefully matched in hopes of yielding a robust and useful offspring. When typefaces Roundup with fat, rounded serifs and WyomingSpaghetti with fat, squarish serifs were chosen to be parents, it was clear that their offspring would inherit large serifs. But to discover exactly what the offspring would look like, the pairing needed to be consummated, which was done with the "Blend Fonts" commend in Fontographer. The two styles of RoundWhy are the result.
