adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolyploidy - individual or strain whose chromosomes are composed of more than two genomes each of which has been derived more or less complete but possibly modified from one of two or more species -matin...

bio 181 exam 1 (kosal)Compare and contrast the different mechanisms of speciation (allopatric, sympatric, parapatric, peripatric). - correct answer -Allopatric speciation takes place when populations are geographically isolated. Volcano explodes and populations are divided. -Sympatric occurs without geographic isolation. Occurs through the process of polyploidy: producing individuals with more than two sets of chromosomes. It is a genetic change within a population. -Parapatric speciation ...
