Question

Quizplus · Accepted Answer

Polyploidy can lead to the formation of new species in just one generation, but complete reproductive isolation typically takes at least two generations. In the first generation of polyploids, mating with diploid individuals may result in triploid offspring, which are often sterile. However, in the second generation, polyploids can mate with each other, leading to the production of fertile offspring with a complete set of chromosomes, which can only mate with other polyploids, completing reproductive isolation.
