How the two species may have formed
NettetFigure 18.16 Alloploidy results when two species mate to produce viable offspring. In this example, a normal gamete from one species fuses with a polyploidy gamete from another. Two matings are necessary to produce viable offspring. The cultivated forms of wheat, cotton, and tobacco plants are all allopolyploids. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/formation-of-new-species/
