We first aimed to establish the incidence of offspring sex bias in Australian E. hecabe, as expressed among broods of two tropical populations obtained over successive years. We next sought to test whether sex biases exhibit the maternal inheritance and antibiotic sensitivity characteristic of ...
We estimated the risk of psychiatric and academic morbidity associated with advancing paternal age using several quasi-experimental designs, including the comparison of differentially exposed siblings, cousins, and first-born cousins. Exposure Paternal age at childbearing. Main Outcomes and Measures ...
Traits like intelligence and ambition are ranked highly by both parents and offspring, as are kindness and understanding (Fugère, Doucette, Chabot, & Cousins, 2017; Perilloux et al., 2011). Other studies have indicated that parent and offspring preferences are more aligned when offspring have ...
First, we included cousin comparisons. Although they rule out less familial confounding by design (because of differences among sisters in the maternal generation), cousin comparisons are less likely to be biased by carryover effects. Cousins are also more likely to be differentially exposed, which...
First, we test for fertility effects of (grand)mother/(grand)mother-in-law presence on i) the probability and timing of first birth and ii) probabilities of subsequent births of grandoffspring and birth spacing. We used time-event models, as these analyses take into account age-specific ...
The researchers suggest that one reason for the reduction in offspring fertility could be mutations occurring in the father's sperm as he ages, which could somehow impact the ability of their children to have children themselves. Another possibility is that older fathers may have less involvement ...
The first reaction of the catabolic pathway of cholesterol is catalyzed by CYP7 and serves as the rate-limiting step and major site of regulation of bile acid synthesis in the liver. A common A to C substitution at position -204 of the promoter of CYP7 gene has been associated with ...
However, an 11-fold higher risk of first relative marriages among parents once the paternal and maternal grandparents were first-cousins and the father was illiterate (aOR=11.01). Moreover, the authors reported a diabetes risk of more than 14 times when the effects of...
After inbred lines had been established following crossbreeding individuals with these two mutations, two females (related cousins) with deviant vocalisation appeared among the descendants in 1957. Whereas the normal threatening call of Microtus arvalis is a monosyllabic, loud and shrill squeak (...
