Why can polyploidy individuals lead to speciation fairly quickly?

In species with polyploid, there are more chromosomal sets than in diploid one. Becouse there are more chromosomal structures available,  events like mutation, recombination, DNA lose, are more probable to occur.

As the generations pass, the accumulation of these changes tend polyploid to speciation.

the answer is g1

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
