Several new tetraploid species of plant known as the salsifies have arisen inwestern North America from diploid species by allop
olyploidy. This mode ofspeciation is known as ________ and it occurs ________. (1 point) a. allopatric speciation; almost instantaneouslyb. allopatric speciation; very slowlyc. sympatric speciation; almost instantaneouslyd. sympatric speciation; very slowlye. adaptive radiation; very slowly
When new specie is evolved from the ancestral species which are surviving, this type of specification is called as Sympatric Speciation. Both ancestral and evolved new specie continue to live in the same geographical area. For example
In the question above a new tetraploid species of plant known as the salsifies have evolved in western North America from ancestral diploid species by allopolyploidy.
