BASIC DOGMAS. "For more than a century the basic tenets for the advantages of sexual reproduction have been that it can serve to (i) generate progeny with a diversity of novel genotypes and (ii) purge the genome of deleterious mutations, such as transposable elements, which otherwise would accumulate inexorably via Muller’s Ratchet to degrade the integrity of the genome." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

COST-BENEFIT RATIO. "Most higher eukaryotes engage in sexual reproduction, at least part of the time." http://onlinelibrary.wiley.com/doi/10.1002/ece3.1516/full View in LinkedIn

BENEFITS OF SEXUAL REPRODUCTION. "Given the ubiquity of sexual reproduction, combined with the fact that the few known truly asexual lineages appear to be of relatively recent origin and therefore may be doomed to more rapid extinction, it is expected that sex must confer benefits." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

SPECIES AS UNIT OF SELECTION. "However, despite numerous experimental studies, such pressures in favor of sexual lineages have never been demonstrated. It would thus be a selection at the species level: a selection for species unable to lose sex because of constraints, and not a short-term advantage of sex." https://lnkd.in/dV7ZdGm View in LinkedIn

THE FECUNDITY OFFSET. The conundrum for facultatively sexual organisms: “Why engage in sex if very few of your progeny might even attain the well adapted genotype of either parent? One way to obviate this cost is to have very many progeny, such that at least one approximates the fitness of the most fit parent." http://www.mycologia.org/content/105/1/1.full View in LinkedIn

FITNESS ADVANTAGE OF SEX. "The observed advantage in fitness of naturally occurring, sexually derived genotypes over asexually derived genotypes during adaptation reaches 30%–50%, but this underestimates the difference in fitness between “high-sex” genotypes and “low-sex” genotypes." https://lnkd.in/ePUmiA8 View in LinkedIn

ALLELE DIVERGENCE. "Though sex does not immediately affect allele frequencies, it alters the genetic variance, which allows subsequent selection to cause allele frequencies to diverge between more versus less sexual lineages." https://lnkd.in/ePUmiA8 View in LinkedIn

SEX WINS. "The redistribution of alleles through sex can result in the variance of sexually derived offspring being different (higher or lower) than that of asexually derived offspring." https://lnkd.in/ePUmiA8 View in LinkedIn

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