All the answer choices are correct.

Polyploidy can lead to speciation, and thus it is a type of sympatric speciation. It is prevalent in ferns, where it occurs in about 95% of species. Polyploidy results from a duplication of chromosomes, leading to an increase in the number of chromosomes in a cell. This process occurs naturally in about 50% of all plant species, and it is a significant factor in plant evolution and diversification.
