One leads to allopatric speciation, whereas the other leads to sympatric speciation. b. One involves the movement of the organism, whereas the other involves a change in the environment. c. One depends on a genetic mutation occurring, whereas the other does not. d. One involves closely related organisms, whereas the other involves only individuals of the same species.arrow_forwardWhat is required for sympatric speciation to occur? A. Continuous gene flow between different populations B. Geographic separation of populations C. Two populations that are different begin to reproduce and create hybrids D. Emergence of a reproductive barrierarrow_forward
- Which of the following could result in allopatric speciation? A. Two populations of a species are separated by a river that they are unable to cross. B. Two populations of a species are separated by a field that is too dry during the summertime. C. One group within a population mates during the evenings and another during the mornings. D. One group within a population develops a new mating ritual that is not recognized by the other.arrow_forwardThe difference between sympatric and parapatric speciation is_______ . a. parapatric speciation occurs only in velvet walking worms b. sympatric speciation requires a barrier to gene flow c. the extent of overlap in range d.reproductive isolation does not occurarrow_forwardA physical barrier separates a single species, causing two separate populations to form. Over time these two populations adapt to their environments. Eventually, these two populations are no longer able to successfully reproduce with each other. This is known as __________. A. Sympatric speciation B. Allopatric speciation C. Autopatric speciation D. Parapatric speciationarrow_forward
