The origin of a new plant species by hybridizing two existing species, coupled with accidents during cell division, is an example of ________.
A) allopatric speciation and autopolyploidy
B) sympatric speciation and allopolyploidy
C) allopatric speciation and allopolyploidy
D) sympatric speciation and autopolyploidy

Question

Quizplus · Accepted Answer

Sympatric speciation occurs when a new species evolves from a single ancestral species while inhabiting the same geographic region. Allopolyploidy refers to polyploidy (having more than two paired sets of chromosomes) resulting from the hybridization of two different species. This combination of sympatric speciation and allopolyploidy accurately describes the scenario of a new plant species originating from the hybridization of two existing species, along with chromosomal duplication errors.
