Polyploidy Study guides, Study notes & Summaries

Macroevolution changes in a population over very long periods of time. Speciation the splitting of one species into two or more new species Biological Species Concept offers testable way to define a species that does not depend on appearance: The members of a species interbreed and have a shared gene pool, & each species is reproductively isolated from every other species. Gene flow occurs between the populations of a species, but not between pops of diff species. Biolo...
