- 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 inviabilityWhich 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 aboveGive 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 attached
- Explain the difference in behaviors of temporally isolated species when it comes to Allopatric vs Sympatric speciation.give examples of allopatric and sympatric speciationThe first step leading to allopatric speciation is (a) hybrid inviability (b) hybrid breakdown (c) adaptive radiation (d) geographic isolation (e) paedomorphosis
- Indicate 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 condition in which there are barriers to successful interbreeding between individuals of different species in the same community is referred to as * latent variations sterility structural differences reproductive isolationDefine co-speciation
- Of the following species concept, which one emphasizes reproductive isolation as the major cause for speciation? Phylogenetic species concept Morphological species concept Biological species concept Evolutionary species conceptSpeciation Mating at different times of the year is a barrier to reproduction. postzygotic O prezygoticA ring species is composed by populations arranged in a circle around a barrier with one boundary characterized by reproductive isolation. It is an example of: ORIGINAL POPULATION GENE FLOW FAILURE TO REPRODUCE GEOGRAPHIC BARRIER Allopatric speciation Sympatric speciation Ecological speciation Isolation by distance
