A BETTER LIFE. "An evolutionary advantage may accrue to allopolyploids from higher rates of population establishment and persistence. This may occur because genome doubling, especially when two divergent genomes are present, provides an immediate vehicle for transcending parental niches." https://lnkd.in/eee56_B View in LinkedIn

FRESH GENES. "Greater niche differentiation between progenitor and neopolyploid increases the proximity and opportunity to mate with other neopolyploids, a key factor in polyploid establishment." https://lnkd.in/eee56_B View in LinkedIn

"NICHE DIVERGENCE may lead to less competition with progenitors or to a competitive advantage, and correlatively higher levels of population growth, which is essential if new populations are to survive in the face of demographic and environmental stochasticity." https://lnkd.in/eee56_B View in LinkedIn

FRESH TERRITORIES. "Polyploids with two or more genomes seem especially adept at colonizing habitats which are beyond the tolerances of their progenitors. An establishment advantage might also accrue for allopolyploids when neoautoploids have lower fertilities than neoalloploids." https://lnkd.in/eee56_B View in LinkedIn

STRESS TOLERANCE. "Allopolyploids may also endure environmental change better than autopolyploids, because the former may marshal more genetic resources through genome reorganization and greater flexibility in gene expression to cope with immediate stresses." https://lnkd.in/eee56_B View in LinkedIn

"LOGIC is not a substitute for data; and substantial data are lacking for many aspects of polyploid evolution." https://lnkd.in/eee56_B View in LinkedIn

PLANT REPRODUCTION. "Flowering plants display a variety of sexual systems, ranging from complete cosexuality (hermaphroditism) to separate-sexed individuals (dioecy). While dioecy is relatively rare, it has evolved many times and is present in many plant families." https://lnkd.in/e-bMaHt View in LinkedIn

"TRANSITIONS in sexual systems are hypothesized to be affected by large genomic events such as whole-genome duplication, or polyploidy, and several models have been proposed to explain the observed patterns of association." https://lnkd.in/e-bMaHt View in LinkedIn

PLOIDY AND REPRODUCTION. "We conclude that the long-hypothesized connection between ploidy and sexual system holds in some clades, although it may well be affected by factors that differ from clade to clade." http://www.amjbot.org/content/103/7/1223.short View in LinkedIn

NOT THERE YET. "Our results further demonstrate that to better understand the evolutionary processes involved, more sophisticated methods and extensive and detailed data sets are required for both broad and focused inquiry." http://www.amjbot.org/content/103/7/1223.short View in LinkedIn
