The polyploids that arise within a species are known as autopolyploids, and those that arise from the hybridization of two different species are known as allopolyploids.
Homoploid hybridization is also known as recombinational speciation.
Allopolyploidy is a type of polyploidy in which two individuals that belong to two different species produce a hybrid individual.
This hybrid individual which is formed undergoes duplication of the genome and forms a new species or individuals.
