Alloploidy Definition:
Various mechanisms can change a sterile hybrid into a fertile polyploid called an allopolyploid. allopolyploids are fertile when mating with each other but cannot interbreed with either parent species; thus, they represent a new biological species.

Alloploidy Notes:
The allopolyploid nucleus also has multiple copies of the genome. This happens when more than the required number of species contributes to the nucleus chromosomes. For example, we could consider the grain wheat. This wheat is a cross between three types of grasses. Since all the three types are contributing, they hold six set of chromosomes. Each set of chromosome has one homologous pair. This makes them perfect for a complete meiosis.
