Aggression mediates competition for food, mating partners, and habitats and, among social animals, establishes stable dominance hierarchies. In humans, abnormal aggression is a hallmark of neuropsychiatric disorders and can be elicited by environmental factors acting on an underlying genetic susceptibility. Identifying the genetic architecture that predisposes to aggressive behavior in people i...
HE yeast Saccharomyces cerevisiae normally alternates between haploT phase and diplophase, propagating vegetatively primarily as a diploid (WINCE 1935). SUBRAMANIAM and coworkers ( SUBRAMANIAM and KRISHNA MURTHY 1949; MITRA and SUBRAMANIAM 1949 ; SUBRAMANIAM 1951) have reported the production of tetraploids by the exposure of diploid yeast to acenaphthene and chrysene. Their data lack any genet...
a r t i c l e i n f o The Dark Triad (narcissism, Machiavellianism and psychopathy; DT) and mating effort are associated with antisocial behaviour, but these associations may build on underlying personality traits not specific to violence. The DT (measured using the SD3), the HEXACO personality scale, and a measure of mating effort were regressed onto a measure of self-reported violence as defi...
the group size and behavior of goitered gazelle was studied over the year 2001 in kalmand-bahadoran protected area. gazelle groups showed no stable organization in kalmand protected area. in spring season, group size was smaller than other seasons and the largest groups were seen in winter. number of solitary gazelles increased during the mating season. adult males were territorial in mating se...
in this research, two mating schemes for the management of recessive genetic disorders affecting abortion in a dairy cattle population were simulated. the first mating scheme was performed under three different scenarios: 1. the mating of a pair of two carriers of the same lethal haplotype was avoided. 2. it was avoided matings in which the service sires and cow's sire carried the same let...
to evaluate fertility status and mating type distribution of cryphonectria parasitica, causal agent of chestnut blight in guilan province, four sites in two main growing regions of: shaft (visrud, taleghan and babarekab), and rezvanshahr (doran) were investigated. during the study, fifty four isolates of c. parasitica were examined. c. parasitica isolates were crossed with each of the two matin...
If mating with an inferior male has high fitness costs, females may try to avoid mating with these males. Alternatively, females may accept an inferior male to ensure they have obtained at least one mate, and/or to avoid the costs of resisting these males. We hypothesized that females compensate for mating with an inferior male by remating. We tested this hypothesis by measuring remating propen...
introduction: codling moth, cydia pomonella is one of the key pests of apple in khorasan razavi province which annually causes severe fruit damage to apple crop. there are several ways that are used to control and prevent injury to apple products in the world. the most successful and widespread use of pheromones has been in monitoring traps. mating disruption method by pheromones takes place wh...
