We have identified, using composite interval mapping, quantitative trait loci (QTL) affecting a variety of life history traits (LHTs) in the nematode Caenorhabditis elegans. Using recombinant inbred strains assayed on the surface of agar plates, we found QTL for survival, early fertility, age of onset of sexual maturity, and population growth rate. There was no overall correlation between survi...

Quantitative traits have long been hypothesized to affect speciation and extinction rates. For example, smaller body size or increased specialization may be associated with increased rates of diversification. Here, I present a phylogenetic likelihood-based method (quantitative state speciation and extinction [QuaSSE]) that can be used to test such hypotheses using extant character distributions...

The present study insights into the interrelationships and taxonomic segregation of some Polypodiaceous fern taxa based on leaf architecture foliar micro-morphology. Twenty-seven species were examined valuable qualitative quantitative data obtained to generate UPGMA dendrogram. A dichotomous key differentiating was prepared. Results reveal that even though have overlapping characters, certain s...

Despite the success of genome-wide association studies, much of the genetic contribution to complex human traits is still unexplained. One potential source of genetic variation that may contribute to this "missing heritability" is that which differs in magnitude and/or direction between males and females, which could result from sexual dimorphism in gene expression. Such sex-differentiated effe...

Dichotomous thinking is a propensity for individuals to understand events as opposites, in binary way. There are currently two inventories that accurately measure this construct, the Thinking Inventory, and Eating Disorders Scale. The present study aimed carry out review process compile all empirical studies have made use of either these instruments. To achieve goal, we carried scoping review. ...

Recent advances in genotyping technology make it possible to utilize large-scale association analysis for disease-gene mapping. Powerful and robust family-based association methods are crucial for successful gene mapping. We propose a family-based association method, the generalized disequilibrium test (GDT), in which the genotype differences of all discordant relative pairs are utilized in ass...
