Two inbred strains of Tsukuba Emotionality Rat (THE and TLE) and four hybrids derived from them were observed for ambulatory response in a novel environment as a measure of emotionality. The Runway Test (modified "timidity test") was run for successive three days. Mean transformed (square root) scores of ambulation for generation were subjected to Mendelian cross analysis. Total ambulation scor...

A selective sweep describes the reduction of linked genetic variation due to strong positive selection. If s is the fitness advantage of a homozygote for the beneficial allele and h its dominance coefficient, it is usually assumed that h=1/2, i.e. the beneficial allele is co-dominant. We complement existing theory for selective sweeps by assuming that h is any value in [0, 1]. We show that gene...

I uncover a new force towards increasing dominance (the property whereby, in dynamic games, the leader tends to increase his or her lead in expected terms). The new effect results from the strategic choice of covariance in races. I assume that players must choose not the amount of resources to spend but how to allocate those resources. I show that, in equilibrium, the laggard chooses a less pro...

An environmental bacterial mixed culture, Consortia Culture (CC), was employed in this study to assess and demonstrate the extent of Cr(VI) reduction and uptake by cells at concentrations ranging from 1 to 100 mg L . Growing (active) cells of CC displayed higher overall mean Cr uptake (50.74 mg g DW), with 1 1 elevated mean Cr reduction (0.1021-1.5379 mg g h ) and accumulation rate of 0.1988-3....

The genomes of all organisms are subject to continuous bombardment of deleterious genomic mutations (DGM). Our ability to accurately estimate various parameters of DGM has profound significance in population and evolutionary genetics. The Deng-Lynch method can estimate the parameters of DGM in natural selfing and outcrossing populations. This method assumes constant fitness effects of DGM and h...
