NON-RANDOM CROSSOVERS. "Crossover interference, where a cross-over in one position strongly reduces the likelihood of another cross-over occurring in the vicinity and/or on the same bivalent, meaning that the distribution of multiple cross-overs are non-random, is widespread" https://lnkd.in/e2tp_G5 View in LinkedIn

KEY EXCHANGE. "An ubiquitous feature of meiosis is the exchange of genetic material between homologous chromosomes." https://lnkd.in/e2tp_G5 View in LinkedIn

PARENT-OFFSPRING CONFLICTS. "Parents make decisions of allocations to offspring before the "meiotic veil of ignorance", whereas offspring compete for resources “from behind the veil”. These parent-offspring conflicts are likely at the origin of parental imprints that occur on some genes at or just before meiosis." http://biorxiv.org/content/biorxiv/early/2016/04/28/050831.full.pdf View in LinkedIn

“FAST REPRODUCTIVE STRATEGIES (R STRATEGIES) are used by mice and rabbits to make many offspring quickly. Typically, these organisms are small, live short lives and rapidly come to sexual maturity. Their numerous offspring are swiftly independent, with low survivorship.” https://lnkd.in/e3_feD9 View in LinkedIn

ANISOGAMY. "It is widely believed that a disadvantage of sexual reproduction is that a sexually reproducing organism will only be able to pass on 50% of its genes to each offspring. This is a consequence of the fact that gametes from sexually reproducing species are haploid. This, however, conflates sex and reproduction which are two separate events. The "two-fold cost of sex" may more accurately be described as the cost of anisogamy. Not all sexual organisms are anisogamous." https://en.m.wikipedia.org/wiki/Evolution_of_sexual_reproduction#Two-fold_cost_of_sex View in LinkedIn

SEXUAL POLYGAMY. “Polygyny is one male with many females (lions) versus polyandry or one female with many males (bees). Many primates and dolphins are promiscuous, with multiple indiscriminate matings.” https://lnkd.in/e3_feD9 View in LinkedIn

ASEXUAL ADVANTAGE. "In most multicellular sexual species, the population consists of two sexes, only one of which is capable of bearing young (with the exception of simultaneous hermaphrodites). In an asexual species, each member of the population is capable of bearing young. This implies that an asexual population has an intrinsic capacity to grow more rapidly with each generation." (John Maynard Smith). https://lnkd.in/eQbyfmX View in LinkedIn

SEXUAL MONOGAMY. Over 90% of birds mate with a single mate for more than one breeding season, including eagles, albatross, swans, and swallows. These require more extended rearing of the offspring. https://lnkd.in/e3_feD9 View in LinkedIn

TWO FOLD COST. "The evolution of sexual reproduction is a major puzzle for biologists. The two-fold cost of sex is that only 50% of organisms reproduce and organisms only pass on 50% of their genes." https://lnkd.in/e3hvRP7 View in LinkedIn

ALLOGAMY VS AUTOGAMY. “Allogamy" (cross-fertilization) is a term used in the field of biological reproduction describing the fertilization of an ovum from one individual with the spermatozoa of another. By contrast, autogamy is the term used for self-fertilization.” https://en.m.wikipedia.org/wiki/Allogamy View in LinkedIn
