Randler (2008), in his meta-analysis of avian hybrid zones, concluded assortative mating was stronger in narrow hybrid zones compared to wider ones.
This allows us to approximate the extent of assortative mating from a frame of reference that has not been accomplished in previous research.
Alternatively, we acknowledge the possibility that the earlier arrival of white-striped females demonstrated in our study is merely facilitated by their larger size and may have no functional significance in negative assortative mating or dominance relationships.
While the descriptive assortative mating patterns are not statistically different by treatment status, they may be correlated with other characteristics of the partners which will to be addressed in a multivariate setting in the next section.
Nonrandom mating is simulated by using a slider on the interface to adjust the probability of positive assortative mating (value > 0) or negative assortative mating (value < 0), such that individual fish have a greater probability of mating with individuals of the same or different genotype than expected by chance (value = 0).
Assortative mating directly on health behaviors could occur.
A centralized one, such as incest prevention or assortative mating incurs high overhead in global comparison.
So The aim of this study was to investigate (1) if there also exists assortative mating phenomenon between species of scallops as found in other marine invertebrates; (2) to what degree the presence of conspecific sperms affect the cross-fertilization success of interspecific sperm and (3) to what extent this assortative fertilization can be affected by environmental factors, such as temperature and salinity, so that measures may be taken to improve the scallop hybridization program.
The authors show that, under basic assumptions of assortative mating, a comparison of the rates of change over time in the probability that a woman enters her father's occupation relative to her father-in-law's occupation can be used to test whether there has been increased transmission of occupation-specific human capital.
Using DXA, they were found that assortative mating for body fatness was not linked to the length of time that a couple had lived together.
Which functions other than professional discipleship, tenured faculty positions, and encouraging assortative mating are the sole preserve of the research university?
Called assortative mating, this is a critical factor in maintaining genetic differences among geographically mingled races.
