This paper proposes the generalized Trivers-Willard hypothesis (gTWH), which suggests that parents who possess any heritable trait which increases male reproductive success at a greater rate than female reproductive success in a given environment will have a higher-than-expected offspring sex ratio, and parents who possess any heritable trait which increases female reproductive success at a gre...

The study included 1,596 newborns and their parents living in Sibenik County, Croatia. All newborns are born between 37 and 42 weeks of gestation, with no congenital anomalies and from a single pregnancy. Fathers and mothers of male babies are older than those of girl babies (p < 0.01). Mean values for weight, height, BMI in parents and the woman's parity are equal (p = 0.05). Pregnancy with ma...

The current study tested the degree to which mindfulness in parents was directly and indirectly related to stress levels in children. A community sample of 68 parent-child dyads completed selfreport surveys (Children: Mage = 10.70, SD = 2.6; 52% female, 48% male; Parents: Mage = 42.70, SD = 9.6; 72% female, 28% male). Multiple regression analyses revealed that both parent mindfulness and child ...

This study sought to examine parent perceptions of medication use for 151 preschool children (M age  = 5.05 years, 78% male, 82% Hispanic/Latino) with or at-risk for ADHD who were medication naive. Parents completed questionnaires regarding family background and perceptions of medication treatment. Parents and teachers completed ratings of child diagnostic symptomatology, behavioral functioning...

OBJECTIVE We studied the influence of positive family history (FH) of type 2 diabetes mellitus (T2DM) in male offspring using multiple metabolic and endocrine parameters in order to assess whether one or more of these parameters can be used as indicators for T2DM development later in life. DESIGN Fifty male subjects with one diabetic parent (ODP) and thirty with both diabetic parents (BDP) we...

Cognitive ability strongly aggregates in families, and prior twin and adoption studies have suggested that this is the result of both genetic and environmental factors. In this study, we used a powerful design--home-reared and adopted-away cosibling controls--to investigate the role of the rearing environment in cognitive ability. We identified, from a complete national Swedish sample of male-m...

In this study, we considered five categories of molecular markers in clonal F1 and double cross populations, based on the number of distinguishable alleles and the number of distinguishable genotypes at the marker locus. Using the completed linkage maps, incomplete and missing markers were imputed as fully informative markers in order to simplify the linkage mapping approaches of quantitative t...

Over the past 15 years, the grape breeding program at the University of California, Davis, has been evaluating Vitis rupestris x Muscadinia rotundifolia selections for resistance to the dagger nematode, Xiphinema index, and to Pierce’s disease (PD). Selections from these crosses exhibit very strong resistance to X. index and PD. In addition to breeding efforts, populations from these crosses ha...
