REASSEMBLING OUTCROSSING. “The genetic basis and complexity of the outcrossing mechanism are important because they control directly the likelihood that an outcrossing phenotype can be reassembled in a selfing population.” https://lnkd.in/dj9hK7n View in LinkedIn

HYPOTHETICAL. “In the absence of pollinators, reversals would be impossible, with the sole exception of a simultaneous shift to an abiotic mode of cross-pollination.” https://lnkd.in/dj9hK7n View in LinkedIn

A SOURCE OF GENETIC VARIATION. “Sexual reproduction has been observed in nearly all branches of the eukaryotic tree of life. It provides an important mechanism to establish genetic variation by combining genetic information of two parental lineages.” https://lnkd.in/eC8eb-V View in LinkedIn

IMPACT OF POLLINATORS. “Reversals to outcrossing are also unlikely when selfing evolves in pollinator-limited environments, because pollination vectors are necessary to produce outcrossed seed.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

HEART OF EVOLUTION. “Even though chromosomal rearrangements have been associated with diseases and reduced fitness, they are also major drivers of evolution. They contribute to adaptation to novel or changing environments and even to speciation by reproductive isolation.” https://lnkd.in/eC8eb-V View in LinkedIn

STACKED DECK. “Outcrossing mutations would have to overcome both the transmission advantage of selfing and the greater seed production of plants capable of self-fertilization. These are potentially large disadvantages at the gene and individual levels.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

GENOMIC VARIATION. “Variations are caused by a multitude of mechanisms and range from single nucleotide polymorphisms to large-scale genomic rearrangements. The latter may result in translocation, duplication, and deletion of genetic material, thereby affecting chromosomal size and gene content.” https://lnkd.in/eC8eb-V View in LinkedIn

MORE RESTRICTIVE. “If selfing evolves because of reproductive assurance, the conditions for a reversal are even more restrictive than if selfing evolves principally because of its transmission advantage, assuming that all else is equal.” https://lnkd.in/dj9hK7n View in LinkedIn

DYNAMIC GENOMES. “Genomes are highly dynamic and vary considerably between, and often even within, species with respect to structure and content. This dynamics is caused by mutations that are either neutral, and may thus be transient, or mediate increased fitness and became fixed in the population by natural (Darwinian) selection.” https://lnkd.in/eC8eb-V View in LinkedIn

AMPLIFIED PENALTY BOX. “Although reversals to outcrossing are generally viewed as unlikely because of the concurrent reduction in outcrossing rate and inbreeding depression, it is widely underappreciated that the ecological context may amplify the costs of outcrossing.” https://lnkd.in/dj9hK7n View in LinkedIn
