An assortative pairing is another name for an associative mating, the mutual attraction or selection of individuals with similar characteristics for reproductive purposes.
Assortative mating is when individuals with similar traits are more likely to form relationships. This can lead to the reinforcement of certain traits within a population.

Assortative mating. Hardy-Weinberg condition, which are never met in the wild, posit random mating. We know that sexual selection does not tolerate random mating and female choice is a great driver of selective change in most organisms.

What all the ideal non-real conditions of the Hardy-Weinberg equilibrium predict; no evolution takes place. Mating is assortative, non-random in the real world and sexual selection is at work when assortative mating takes place, thus evolution.
This is known as assortative mating, where individuals choose partners based on specific traits that are heritable. This can lead to the reinforcement of those traits within a population over generations.
Gene flow that involves the movement of individuals from a high-variation population into a low-variation population can result in a reduction of genetic variation. This can happen if the incoming individuals do not introduce new alleles or if genetic drift and selection reduce the frequency of existing alleles.
There is gene flow between populations, mating is assortive and natural selection is taking place from the variations offered un by recombination and mutation. Thus, alleles are changing frequency in the population of rats and negating Hardy-Weinberg constraints.
According to the Hardy-Weinberg principle, the frequency of alleles in a population will remain constant from generation to generation as long as equilibrium is maintained through random mating, no gene flow, no genetic drift, no natural selection, and no mutations.
The principle of segregation and the principle of independent assortment would apply. The principle of segregation states that each parent contributes one allele for each trait, and the principle of independent assortment states that alleles for different traits are inherited independently of each other.
The anus is not for mating.
