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

SELF-INCOMPATIBILITY. “At one end of the spectrum of complexity, self-incompatibility systems involve closely co-evolving pistil- and pollen-expressed genes. The derivation of selfing in ancestrally self-incompatible lineages causes the loss of tightly co-evolved allelic diversity in the genes embedded at the S-locus.” https://lnkd.in/dj9hK7n View in LinkedIn

PREVENTION OF SELFING. “Morphological adaptations that prevent self-pollination (e.g. flower size, dichogamy or herkogamy) may involve a much smaller loss of complexity.” https://lnkd.in/dj9hK7n View in LinkedIn

NO NEED TO ATTRACT POLLINATORS. “The suite of morphological adaptations that accompanies shifts to self-fertilization, and comprises the ‘selfing syndrome’, is dominated by quantitative reductions in the size of floral organs.” https://lnkd.in/dj9hK7n View in LinkedIn

LESS DIVERSITY. “Selfing may constrain adaptive evolution by reducing the levels of polymorphism and, particularly, additive genetic variation.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

LESS POLYMORPHISM. “There is considerable support for the notion that selfing lineages harbor less nucleotide polymorphism, although it is unclear how genome-wide nucleotide polymorphism is linked to potential adaptive phenotypic evolution.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

WARM FOOTPRINT. “Selfing may limit purifying or positive selection, but these lineages may not persist long enough to leave footprints of attenuated adaptation in the genome. Phylogenetic studies have shown that the origins of selfing are often rather recent.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

DATA BUCKET. “With over five decades in their wake, modern studies of plant mating system evolution have yielded data on selfing and outcrossing rates for approximately 500 species and numerous analyses of the history of mating systems, employing a variety of formal models and theoretical and empirical arguments.” http://onlinelibrary.wiley.com/doi/10.1111/nph.12182/full View in LinkedIn

ADAPTATION. “All species continuously evolve to adapt to changing environments. The genetic variation that fosters such adaptation is caused by a plethora of mechanisms, including meiotic recombination that generates novel allelic combinations in the progeny of two parental lineages.” https://lnkd.in/eC8eb-V View in LinkedIn

CONSIDERED POORLY ADAPTABLE. “A considerable number of eukaryotic species, including many fungi, do not have an apparent sexual cycle and are consequently thought to be limited in their evolutionary potential. As such organisms are expected to have reduced capability to eliminate deleterious mutations, they are often considered as evolutionary dead ends.” https://lnkd.in/eC8eb-V View in LinkedIn
