An isolation wherein there's a differences in reproductive organs prevent successful Interbreeding. 12. It means "near" 14. Prevents the formation of fertile offspring 15. Formation of new species from the hybridization of 2 different speciesWhich 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 aboveOver many generations, there is a good chance that an advantageous gene will be shared by every organism of the same species or that a new species will emerge. These long-term outcomes are called: population evolution hybridization adaptation
- A genome duplication event, creating a tetraploid plant from a diploid parent plant, can sometimes result in the creation of a new species. This type of speciation is called allopatric adaptive radiation sympatric gradual speciation Which of the following is an example of a postzygotic barrier? Hybrid offspring of two species of jimsonweeds always die before reproducing One plant lives on acid soil, the other on alkaline soil. Two species of leopard frogs have different mating calls Mallard and pintail ducks mate at different times of the year Pollen of one species of tobacco cannot fertilize a different species of tobacco.Assume you are studying secondary contact in two species of birds. You notice that hybrids are produced and that much of the DNA of each species is becoming more similar over time. The likely end point of this process is which of the following? Fusion Evolution of reproductive isolation Reinforcement Stable and minimal hybrid productionUnder which of the following conditions is a population most likely to evolve? phenotypic variation random mating no gene flow a large population genetic drift What does hybrid sterility refer to? temporal isolation mechanical isolation allopatric speciation a prezygotic isolating mechanism none of the above
- Assume you are studying a population of ocean shrimp that reproduce asexually. You sequence the ocean shrimp and the species that is their closest living relative that reproduces sexually. You find that the asexually reproducing species has a higher number of mutations in the genome. This finding would provide support for which of the following ideas? Linkage disequilibrium Stabilizing selection Disruptive selection Muller's ratchetGray aphid (sap sucking insects) had offspring that evolved into red aphids through horizontal gene transfer of carotenoid genes from a fungus. These genes can produce yellow, green and red pigments after the gene duplicated in the aphid genome. Later, biologists discovered pea aphids which only carry the green carotenoids. Which microevolutionary change does the aphid story a good example? microevolution by genetic drift microevolution by horizontal gene transfer microevolution by a single mutation which deleted yellow and red pigment genes to produce green aphids microevolution by a two mutation which initially duplicated carotenoid genes, then deleted yellow and red pigment genes to produce green aphids microevolution by a three mutation which initially occured by horizontal gene transfer, then by duplicated carotenoid genes, then deleted yellow and red pigment genes to produce green aphidsWhat is the nature of the reproductive barrier between a species that mates at dawn (sunrise) and a species that mates at dusk (sunset)? gametic temporal habitat behavioral mechanical A mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the range and brings the two populations together again, but when they mate, the resulting hybrids all produce sterile young. This scenario is an example of allopatric speciation gradualism punctuated equilibrium extinction sympatric speciation
- Which of the following species would have the greatest chance of going extinct? a species with a slow reproduction rate and very little genetic variation living in a changing environment a species with a fast reproduction rate and lots of genetic variation living in a changing environment a species with a slow reproduction rate and very little genetic variation living in a stable environment a species with a fast reproduction rate and lots of genetic variation living in a stable environmenttwo populations of a single species become geographically separated, over time they may diverge into sep © Allopatric Sympatric Physiological © All of the aboveYou are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. Microevolution is occurring in both variations. They are two separate species. Two species of toads are reproductively isolated due to the fact that one species mates in early summer and one in late summer. Both species of toads evolved from a common ancestor. What type of speciation occurred?* OAllopatric
