Polyploidy speciation Definition:
A species may originate from an accident during cell division that results in extra sets of chromosomes, a condition called polyploidy.

Polyploidy speciation Notes:
By definition, polyploidy just means that a cell or organism contains more than 2 pairs of homologous chromosomes (or is more than 2n). This is more common in plants than it is in animals. Multiple plants within a population can end up with the same polyploidy number. They can then reproduce with each other but not with the original plants or any other plants. As a result, they become biologically isolated from the original group of plants and are considered a different species.
