Because you can't tell someone's life span in advance, assortative mating
in humans must be based on other characteristics.
They concluded that such similarities in the couple were likely because of positive assortative mating
, that is the selection of partners based on similar risk preferences.
As there does not appear to be assortative mating
between these species pairs (Field and Jarman 2001, Morgan-Richards et al.
Finally, much more sophisticated measures of assortative mating
(e.g., twin studies, linkage analysis, and genome-wide association studies) should be considered to confirm findings on matching by behavioral health indicators among military couples.
The rationale behind the household-specific effect is that it will partially capture ability, at least at the household level, rationalized for example by the presence of assortative mating
and/or genetic endowments or, more generally, intergenerational transmission of human capital.
The values of the ISI range from -1 ("complete negative assortative mating
", i.e., adults only mate with partners from the opposite strain or population), through an equilibrium at 0 ("random mating", i.e., uniform sexual compatibility and therefore no mating preferences), to +1 ("complete positive assortative mating
", i.e., adults only mate with partners from the same strain or population resulting in complete mating isolation).
and Differential Fertility by Phenotype and Genotype across the 20th Century D.
It also involves a much greater degree of assortative mating
, in which elites marry similarly well-educated partners, and men and women more carefully choose spouses who will complement their choice of family roles in an era in which two incomes have become increasingly important.
Patton's brassy indifference to delicacy served the serious purpose of riveting attention on what social scientists call ''assortative mating

In "Marry your like: assortative mating
and income inequality" (National Bureau of Economic Research working paper 19829, January 2014), authors Jeremy Greenwood, Nezih Guner, Georgi Kocharkov, and Cezar Santos find that assortative mating
is important for income inequality, and that income inequality in the United States has increased since 1960, in part because of more women entering the workforce.
There is a number of mating patterns in humans and one of them is assortative mating
, which appears if individuals mate with others based on similarity between one to another.
This suggests that if mass migration were sufficiently common to bring individuals from geographically distinct populations into contact at a specific site, it would very quickly eliminate most of the genetic population structure in Junonia at that locality unless there is assortative mating
