Question

Which of the following is a correct comparison between the speciation of the trumpeters of the Amazon and the ongoing divergence of the maggot flies of North America? See Section 24.3 Both events resulted from barriers to gene flow that arose between populations as well as mutations, natural selection, and genetic drift that occurred in those populations. Both events involved a large geographic barrier between populations. Both events involved polyploidization. Both events involved populations that were overlapping in their ranges.

Answer 1
