GENETIC CHEATING. "A striking feature of meiosis is its apparent fairness: under Mendel’s first law of inheritance, each allele has a 50% chance of ending up in any given gamete. However, there are many selfish genetic elements that increase their chances above 50% by subverting the mechanism of meiosis." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

BIOLOGICAL FUNCTION OF SEX? "Why is sexuality (and meiosis) so common? This is one of the important unanswered questions in biology and has been the focus of much research beginning in the latter half of the twentieth century." https://lnkd.in/exK5mn7 View in LinkedIn

LOADED OOCYTES. "In other cases, asymmetrical meiosis in females results in a large oocyte full of resources, which may favour the production of a single cell rather than four." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

“EXTERNAL SEXUAL SEXUAL REPRODUCTION is where the egg is fertilized outside the female, such as in corals, fish, plants, fungi. Aquatic creatures often use this method because their sperm will not desiccate. Broadcast spawning in reef fish often release eggs and sperm simultaneously such as in boxfish, abalone and corals. Demersal spawning involves laying eggs and sperm into a protected place (clownfish).” https://lnkd.in/e3_feD9 View in LinkedIn

“INTERNAL SEXUAL REPRODUCTION is where the sperm fertilizes the egg within the female (mammals, birds, spiders, insects, reptiles). This is suited for terrestrial creatures whose sperm readily dries out and dies.” https://lnkd.in/e3_feD9 View in LinkedIn

“SEXUAL SELECTION among competing males for female impregnation may explain why males exist. It acts as a filter to weed out harmful genetic mutations allowing the survival of the population.” https://lnkd.in/e3_feD9 View in LinkedIn

RED QUEEN HYPOTHESIS. “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, which 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.” https://lnkd.in/etNBEYs View in LinkedIn

“ASEXUAL REPRODUCTION is more efficient than sexual reproduction because sexual reproduction has 50% males who cannot produce offspring themselves. Why do males exist?” https://lnkd.in/e3_feD9 View in LinkedIn

ADVANTAGES OF SEXUAL REPRODUCTION. “The variation that sexual reproduction creates among offspring is very important to the survival and reproduction of the population. In sexual reproduction, different mutations are continually reshuffled from one generation to the next when different parents combine their unique genomes; this results in an increase of genetic diversity. On average, a sexually-reproducing population will leave more offspring than an otherwise similar asexually-reproducing population.” https://lnkd.in/exK5mn7 View in LinkedIn
