Question

3. [4 pts] Montesinos et al (2012) assessed the potential for neoallopatry between native and invasive populations of Centaurea calcitrapa. According to their results (shown at right) and based on our in-class discussion, what can be concluded regarding the level reproductive isolation in this species? Elaborate briefly. What additional data from these seeds would you collect in a simple follow-up experiment to further examine the degree of reproductive isolation between European and American populations of C. calcitrapa? 10 Spain Calfomia Region of polilen recipients

Explanation / Answer

The additional data that we have to collect are genetic drift, adaptation to the different environment, divergent reproductive isolation and the number of the generation that have led to this reproductive isolation and the type of hybridization that has led to this reproductive isolation.

Reproductive isolation can only be possible by removing dispersal barriers.Divergent selection of ecological traits can lead to reproductive isolation. Overlapping distribution is their native range occurs in Spain and non-native range occurs in America(California)
