"Random mating" refers to a situation where individuals in a population choose their mates purely by chance, without any preference or selection based on specific traits or characteristics. Full definition
They are caused by random mating among feral / free - roaming cats with no owners to comply with laws. (cfa.org)
Mating pairs often exhibit levels of similarity in phenotypic or genotypic traits that differ systematically from the level expected under random mating, produced by assortative mating. (genestogenomes.org)
For one such project, the team developed a new software tool called GppFst that allows researchers to differentiate genetic drift — a neutral process whereby genes and gene sequences naturally change due to random mating within a population — from genetic variations that are indicative of evolutionary changes caused by natural selection.
