Objective This article identifies mechanisms through which social class background shapes the marital outcomes of college-going white American women. Background Scholars are interested in relative influences ascriptive and achieved characteristics on mate selection. Research indicates that continues to influence marriage patterns college-educated Americans but does not identify this occurs. Met...

Nine microsatellite markers were isolated from unfed larvae of Ixodes ricinus and were tested on two populations of nymphs collected on roe deer (N=21) and birds (N=39) in a French suburban forest. All markers were polymorphic, with limited evidence for deviations from linkage equilibrium. In accordance with previous markers developed for this species, we found large heterozygote deficits for s...

The choice of ones partner plays an important role on the functionality couple, degree cohesion and chances stability. Theoretically, conjugal in contemporary space is a free one, not conditioned by families, material transactions or other types strategies, that exclude will partners. However, series cultural elements assimilated individuals their social environments consistently mark influence...

Mate choice is the outcome of sexual preference for partners carrying specific signals. Thus, mating among conspecifics (homogamy) depends on the occurrence of species recognition systems. We asked what happens if populations diverge, and we investigated female sexual preference between two subspecies of the house mouse in populations from the borders of a hybrid zone ( Jutland, Denmark). We us...

We propose a new model of permanent monogamous pair formation in zoological populations with multiple types of females and males. According to this model, animals randomly encounter members of the opposite sex at their so-called firing times to form temporary pairs which then become permanent if mating happens. Given the distributions of the firing times and the mating preferences upon encounte...

Research addressing genetic and environmental determinants to antisocial behaviour suggests substantial variability across studies. Likewise, evidence for etiologic gender differences is mixed, and estimates might be biased due to assortative mating. We used longitudinal Swedish total population registers to estimate the heritability of objectively measured violent offending (convictions) in cl...

Sociological theories on family formation and families and health suggest that married and cohabiting partners will resemble each other in health status, positively or negatively. The family is often seen as a health-enhancing agent for individuals. However, there are large health differences among families. This study aims to answer the question whether it is the case that the healthy live wit...
