When on rare occasions the new tetraploid species of plants are formed then the factors that allows the propagation are chromosome nondisjunction, self replication.

So, if a plant produces diploid gametes via nondisjunction and that they self-fertilize, the end result could be a new, tetraploid species. This species is now reproductively remoted from its discern as though the 2 have been to mate they could create nonviable triploid individuals joining of diploid gametes, self-fertilization, chromosome nondisjunction the character has inherited an extraordinary wide variety of chromosome sets (3n, 5n, etc), they're commonly infertile.

This is due to the fact the chromosomes can not pair up successfully at some point of meiosis and hence no purposeful gametes are produced. If the character has a fair wide variety of chromosome sets, they're commonly fertile.
