b. autopolyploidy involves disruptive selection but autopolyploidy does not.
c. if speciation is allopatric rather than sympatric, the mode of speciation is allopolyploidy; if speciation is sympatric rather than allopatric, the mode of speciation is autopolyploidy.
d. in autopolyploidy, one parental species contributes to the polyploidy; in allopolyploidy, two parental species contribute to the polyploidy.
