B) Polyploidy results in decreased rates of speciation.

Question

Quizplus · Accepted Answer

Polyploid individuals have multiple sets of chromosomes, which can result in increased genetic diversity and heterozygosity compared to their diploid relatives. This can provide a genetic advantage and contribute to the process of speciation.
