About 200,000 years ago, Capsella rubella began self fertilizing and split from C. grandiflora. To study the effects of selfing on C. rubella's genome, the Department of Energy Joint Genome Institute ...

Figure 2: Genetic basis of the incompatibility between C. grandiflora and C. rubella.

Species often experience a genetic bottleneck that diminishes genetic variation after speciation or introduction into a new area. Though bottlenecks in population size always reduce fitness and ...

Many plant species have accepted the trade-off between the benefits of greater self-reliance and the disadvantages inherent in inbreeding to switch from outcrossing to self-fertilization. However, ...
