- Which of the following statements about sympatric speciation is correct? It is a process through which two populations can diverge and develop reproductive isolation while in two different geographic area. It is the most common mechanism for populations to form independent species. Postzygotic isolation is the main form of reproductive isolation for the sympatric speciation process. Genetic isolation through large scale chromosomal mutations, such as chromosome inversion or polyploidy, are more likely contributing to sympatric speciation. None of the aboveWhat are characteristics of sympatric speciation? Select all that apply. Reproductive isolation necessary to end gene flow Divergence within a population leads to speciation Absence of a physical barrier Presence of a physical barrier Reproductive isolation unnecessary to end gene flowgive examples of allopatric and sympatric speciation
- One example of coevolution is when speciation within one group of organisms drives speciation within another group of organisms with which it interacts. The term for this type of coevolution is which of the following? Mutualism Antagonism Cospeciation Cooperation ConflictIndicate the order in which the following steps would take place to result in Sympatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] As they adapt to their specific environments, the fitness of any hybrid formed is reduced. Reproductive isolating mechanisms are selected for so that less fit hybrids are not formed. Two species now exist. Interbreeding populations connected via gene flow occur across a range. The populations in the new environment adapt to their particular circumstances while the remainder stay as they were. Something happens so that some members of the populations/species change their environment (shift hosts; have a genetic change like polyploidy or inversions), so that they are separated from the others even thought hey are living in the same area.The reproductive isolating mechanism in which two closely related species live in the same geographic area but reproduce at different times is (a) temporal isolation (b) behavioral isolation (c) mechanical isolation (d) gametic isolation (e) hybrid inviability
- The first step leading to allopatric speciation is (a) hybrid inviability (b) hybrid breakdown (c) adaptive radiation (d) geographic isolation (e) paedomorphosisThe primary mechanism of sympatric speciation is a)dispersal and colonization of new environments b)true or false, Sexual selection may lead to sympatric speciation
- First: Identify the following; allopatric, peripatric, sympatric and parapatric.Second: Explain by giving examples:Why allopatric and peripatric are first affected by geographic isolation, which leads to genetic isolation. On the other hand, sympatric and parapatric are generated from genetic isolation, which then leads to geographic isolation.Give examples on the reproductive isolating mechanisms (geographical isolation, behavioral isolation, mechanical isolation, gametic isolation, temporal or seasonal isolation) Note: example in the activity is in the photo attachedDifferentiate between how prezygotic and postzygotic isolating mechanisms lead to reproductive isolation.
