question 25

Multiple Choice

Which of the following is an example of sympatric speciation?

• A) two populations of salamanders that live on isolated islands and eventually become separate species, unable to interbreed
• B) different breeds of dogs that live in different areas of the world but are able to produce fertile offspring
• C) a horse and a donkey that may interbreed to produce a mule that is sterile and unable to reproduce
• D) two related plant species living in the same area that hybridize, then undergo chromosome doubling, which results in the creation of a third species of plant that is unable to reproduce with either of the two original species
• E) three species that evolve from a common ancestral species due to reproductive isolation and adaptation to different habitats Sympatric speciation refers to populations that develop into two or more new species without prior geographic isolation. Hybridization followed by polyploidy in plants is an excellent example of this type of speciation mechanism.
