Assortative mating

Assortative mating (also referred to as positive assortative mating or homogamy) is a mating pattern and a form of sexual selection in which individuals with similar phenotypes or genotypes mate with one another more frequently than would be expected under a random mating pattern.^[1]

A majority of the phenotypes that are subject to assortative mating are body size, visual signals (e.g. color, pattern), and sexually selected traits such as crest size.^[2] ^{[clarification needed]}

The opposite of assortative is disassortative mating, also referred to "negative assortative mating", in which case its opposite is termed "positive assortative mating".
