Which of the following three statements is/are correct?
I. Speciation through polyploidy can occur through hybridization.
II. Speciation through polyploidy never occurs in vertebrates; it occurs only in plants.
III. Speciation through polyploidy generates phenotypic differences among the resulting species.

Question

Quizplus · Accepted Answer

Statement I is correct because polyploidy can occur through hybridization, where chromosomes from two different species combine to form a hybrid with double the normal number of chromosomes. 
Statement II is incorrect because speciation through polyploidy can occur in both plants and animals, including vertebrates. 
Statement III is correct because polyploid individuals often have different characteristics from their diploid ancestors, leading to the formation of a new species.
