True or False Write true if the statement is true or false if the statement is false.Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation
