1___________Hybridization leads to rapid genomic alterations, including chromosomal rearrangements and gene expression changes, some of which are mediated by not transposable elements.
- ARI
- BFI
- CNI
2___________These genomic changes often result in novel phenotypes, where some of them are intermediate between parentals, some represent novel combinations of parental features, and, finally, others are extreme.
- ARI
- BNI
- CFI
3___________Extreme flowering homoploids can produce a complex blend of floral fragrance that is likely to be effective in attracting pollinators.
- ANI
- BFI
- CRI
4___________In Nicotiana, for example, just one specie in the allopolyploid N. section Repanda has flowers that attract long-tongued night-flying moths (three species) like N. sylvestris (the female parent) or short-tongued bees (one species) like N. obtusifolia.
- ANI
- BRI
- CFI
5___________Sometimes flowers of intermediate morphology and fragrance do not adapt well to any pollinator, especially if there are very specific interactions.
- ARI
- BNI
- CFI
6___________There are specific interactions between the plant and the pollinator, an example of this occurs when the tongue of the nectar spur is highly correlated with the morphology of a specific pollinator.
- ANI
- BRI
- CFI
7___________The hybrid invasion of an alternative niche will be much more successful if it is synchronous after reproductive isolation from its parents.
- AFI
- BNI
- CRI
8___________Recent evidence has not demonstrated the power of hybridization in creating new combinations of traits and genes responsible for niche divergence.
- ANI
- BFI
- CRI

- Descrição
- Based on paragraphs VI, VII and VIII of the section “Pollinator shifts as a mechanism of reproductive isolation hybrids”, write RI for real inference, FI for false inference and NI for not implied inference.
