In Nature, this behavior is known as random mating.
What happens to the allele frequency after one round of random mating?
Cockerham, C.C. & Weir, B.S. Covariances of relatives stemming from a population undergoing mixed self and random mating.
Here we introduce a spatial model of evolution which assumes viability selection, mutations and random mating.
But departures from random mating are actually quite common.
Another type of departure from random mating is inbreeding, or preferentially mating with relatives.
These coefficients are based on the assumption of random mating in the population [48].
The data is inconsistent with clonality, but there are barriers to complete random mating.
For example, shaking of the culture medium generates random meeting, if not random mating, of individuals.
Selfing rate (Fit) will be 33% while random mating means that, by definition, Fis = 0.
Our choice of birth function also implicitly assumes random mating among healthy and parasitized individuals.
