Fragen in diesem Quiz (8)

  1. 1___________Hybridization leads to rapid genomic alterations, including chromosomal rearrangements and gene expression changes, some of which are mediated by not transposable elements.
    1. ARI
    2. BFI
    3. CNI
  2. 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.
    1. ARI
    2. BNI
    3. CFI
  3. 3___________Extreme flowering homoploids can produce a complex blend of floral fragrance that is likely to be effective in attracting pollinators.
    1. ANI
    2. BFI
    3. CRI
  4. 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.
    1. ANI
    2. BRI
    3. CFI
  5. 5___________Sometimes flowers of intermediate morphology and fragrance do not adapt well to any pollinator, especially if there are very specific interactions.
    1. ARI
    2. BNI
    3. CFI
  6. 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.
    1. ANI
    2. BRI
    3. CFI
  7. 7___________The hybrid invasion of an alternative niche will be much more successful if it is synchronous after reproductive isolation from its parents.
    1. AFI
    2. BNI
    3. CRI
  8. 8___________Recent evidence has not demonstrated the power of hybridization in creating new combinations of traits and genes responsible for niche divergence.
    1. ANI
    2. BFI
    3. CRI

Informationen

Beschreibung
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.
