CONTIGUOUS CONDITION. "Recently, it has been shown that sexual selection allows an allele for increased sexual reproduction to invade a facultative population as long as sexual selection and natural selection are acting in the same direction." http://onlinelibrary.wiley.com/doi/10.1002/ece3.1516/full View in LinkedIn

SO ENDS this curation of resource allocation. Sources and sinks in plants is a powerful concept, but equally applies to other kingdoms as well as intracellular competition for limited resources. In recent years we have learned that multicellular organisms are communities of hybrid cells, as well as ecosystems of numerous inhabitants. That competition between hybrids and species exists at all levels is therefore not surprising. View in LinkedIn

COMPETING MALE THEORY. "One likely candidate for influencing the evolution of obligate sex is sexual selection, the process by which individuals of one sex, typically the males, compete over mating opportunities. If individuals pick the best mates they can find rather than mating randomly then sexual populations can gain an advantage over asexual ones." http://onlinelibrary.wiley.com/doi/10.1002/ece3.1516/full View in LinkedIn

DEVELOPMENTAL RIGIDITY. "When a wing imaginal disc of Drosophila is transplanted to the abdomen of an adult fly, it grows to the same size that it would have if it had been left in place in its normal larval environment." http://www.pnas.org/content/95/7/3685.full View in LinkedIn

EVIDENCE OF BENEFIT. "Studies in the model yeast S. cerevisiae by Goddard et al. (2005) provide a direct experimental test for the potential benefits of sex." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

RECOMBINATION. "The evolution of recombination is not the same as the evolution of sex." https://lnkd.in/ePUmiA8 View in LinkedIn

NOVEL GENE SETS. "Genetic recombination is the production of offspring with combinations of traits that differ from those found in either parent. In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on from the parents to the offspring." https://lnkd.in/egNsFFi View in LinkedIn

SEX AND TRAIT SELECTION. "Better support for adaptation providing a “gene-level” advantage to sex comes from survey studies showing that recombination tends to increase as an incidental by-product of directional selection on other traits." https://lnkd.in/ePUmiA8 View in LinkedIn

RED QUEEN "is an allusion to Lewis Carroll’s novel Through the Looking Glass in which the character the Red Queen must run as fast as she can just to stay in the same place, and in the evolutionary analogy sexual reproduction enables organisms to just keep ahead in the co-evolutionary race with the pathogens that afflict them." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

RED QUEEN. "More recently, an additional hypothesis has been advanced that sex might enable organisms to escape or outrun pathogens. This is termed the Red Queen hypothesis." http://www.mycologia.org/content/105/1/1.full View in LinkedIn
