panmixia , także: panmixis

A biological species is a group of individuals which can breed together (panmixia).

The genetic variances also change relative to those of panmixia.

This failure of panmixia leads to two important changes in overall population structure: (1).

The technical term for it is panmixia.

These derive from very small initial populations that must have been viable, and panmixia in the early stages of speciation was usually thorough.

This seems to have been done in the interests of retaining the theoreticians' assumption of panmixia (Charlesworth, 1980).

The mating-system assumed in deriving these genotypic variances is panmixia : which implies random fertilisation with uniform distribution of gametes in a very large population (theoretically, infinity).

Moreover, if the mutant gene confers benefits, such as better camouflage, then affected individuals may out-compete those without the mutation; this would happen faster in a small inbred population close to panmixia.

I was able to show that in any human population, assuming panmixia (random interbreeding), at most 10 percent will manifest a good equilibrium of algedonic control, while the rest must deviate from the norm.

Janet Blyleven would walk into the dining hall with Roger Calkins, and Frank would remark to John, in an undertone meant to reach Maya's ears, "Janet thinks we're a panmixia."

Maya would ignore him, as she always did when he spoke in that sneery tone of voice; but later she looked up the word in a sociobiology lexicon, and found that a panmixia was a group where every male mated with every female.

In simpler terms, it is the ability of individuals in a population to move about freely within their habitat, possibly over a range of hundreds to thousands of miles, and thus breed with other members of the population that defines panmixia (or panmicticism).

Because genotypes are assigned randomly when passed from parents to offspring during meiosis, if we assume that choice of mate is not associated with genotype (panmixia), then the population genotype distribution should be unrelated to the confounders that typically plague observational epidemiology studies.
