Dominance level of insecticide resistance provided by one major gene (an insensitive acetylcholinesterase) in the mosquito Culex pipiens was studied in two distinct environments. Dominance level was found to be very different environments, varying from almost complete dominance to almost recessive when either propoxur (a carbamate insecticide) or chlorpyrifos (an organophosphorus insecticide) w...

In the current study we investigated whether the developmental status of the two largest follicles (LF1 and LF2) at the time of administration of the first two doses (0 and 12 h) of FSH of a superovulatory treatment influences periovulatory events and embryo yields in sheep. A larger size of LF1 was negatively correlated with embryo recovery (r=-0.608 for 0 h and r=-523 for 12 h, p<0.05), ferti...

Brain hemispheric dominance and home environment are student level variables and are of great significance concerning scholastic achievement of the students. Analysis with interaction effect of the Brain hemispheric dominance and home environment with academic achievement in mathematics was ended up in this study and discovers that there is a significant interactional relationship between acade...

generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[sorghum bicolor (l.) moench. six basic generations, namely p1, p2, f1, f2,bc1p1, bc1p2 of four crosses involving seven diverse parents were evaluated inrainy 2009. the mean performance of the f1 in all the crosses indicated dominantgene effect fo...

The challenge hypothesis, conceived for testosterone and vertebrates, has recently been applied to juvenile hormone (JH) and insects. Scott [Scott, M.P., 2006a. Resource defense and juvenile hormone: the "challenge hypothesis" extended to insects. Horm. Behav. 49, 276-281] found that JH in the burying beetle Nicrophorus orbicollis increased in response to a social challenge in the presence of a...

Sibling interaction effects are suggested by a difference in phenotypic variance between monozygotic (MZ) twins and dizygotic (DZ) twins, and a pattern of twin correlations that is inconsistent with additive genetic influences. Notably, negative sibling interaction will result in MZ correlations which are more than twice as high as DZ correlations, a pattern also seen in the presence of genetic...

objective: in recent years different hypotheses with respect to the formation of cerebral laterality were proposed. some of the researchers claim that cerebral dominance and laterality are determined by genetic factors, just as the case with eye color and blood type. however, another group states that in addition to genetic factors, environmental factors, too, have a remarkable role in hemisphe...

BACKGROUND Assessment of three-dimensional kinematics and electromyography (EMG) activities is common in patients with chronic neck pain. However, the effect of hand dominance and neck pain location on the measurement of movement and EMG characteristics is still unclear. Therefore, the purpose of this study was to investigate the effect of neck pain location and arm dominance on the scapular ki...

ran's economy still has a two-digit inflation rate with high fluctuations, which is mainly caused by fiscal dominance. According to the relevant literature, the most important fiscal dominance mechanism is borrowing from the central bank. After prohibiting direct borrowing from the Central Bank by Iran's government, the budget deficits are partially addressed by off-budgeting operations, achiev...
