Polyploidy: a) arises only when there is an error in meiosis resulting in diploid gametes instead of haploid gametes. b) is a common method of sympatric speciation for animals. c) arises when allopatric speciation causes plants to have fewer sets of chromosomes than their parent plants. d) is an increased number of sets of chromosomes. e) always results in allopatric speciation.
Polyploidy that occurs in nature Select one: is thought to be a driving force behind evolution and is the basis for many examples of speciation. is the result of the duplication of a chromosome set in a single species (and does not result from the joining of chromosome sets from different species. is only ever observed in plants; no case of polyploidy in animals has ever been reported. is always associated with sterility in both males and females. only ever results in 3n organisms, or in organisms with an odd number of chromosome sets.
