Match each scenario below with the type of speciation it describes. Group of answer choices:
Allopatric, sympatric, parapatric
a) in a population of orchids, one individual has a new mutation that causes it to flower 3 months
before the rest of the population. The single orchid survives and self-fertilizes, leading over time
to a novel population with larger flowers and smaller leaves. The new population does not
interbreed with the original population, even though they are found in the same areas
b) After an especially severe flood, a river forms. Bird populations on the two sides of the river
are not able to interact with one another or interbreed. Over time, the separated populations
diverge in their mating behavior such that individuals on one side of the river no longer
recognize the birds in the other population as potential mates..
