Answer:
The answer is - Sympatric speciation; almost instantaneously
Step-by-step explanation:
Salsify is a root vegetable that is cultivated for its ornamental flower therefore belongs to the dandelion family. Its scientific name is Tragopogon porrifolius.
Allopolyploidy means having more than two different haploid sets of chromosome obtained from different species.
Sympatric speciation happens when two same groups of species that live in the same geographic region evolve differently until they become different species and can no longer interbreed.
The Salsify initially arose from diploid species that went through allopolyploidy therefore bringing about a sympatric speciation which occurs almost instantaneously.
