The personalities of twins: just ordinary folks.
Twin studies have demonstrated that personality traits show moderate genetic influence. The conclusions drawn from twin studies rely on the assumptions that twins are representative of the population at large and that monozygotic and dizygotic twins are comparable in every way that might have bearing on the traits being studied. To evaluate these assumptions, we used Multidimensional Personalit...
متن کاملEvil twins alternate with odious twins
An integer is called evil if the number of ones in its binary expansion is even and odious if the number of ones in the binary expansion is odd. If we look at the integers between 0 and 15 we find that 0, 3, 5, 6, 9, 10, 12, 15 are evil and that 1, 2, 4, 7, 8, 11, 13, 14 are odious. Next we say that if two consecutive integers are evil then this is a pair of evil twins and that if two consecuti...
متن کاملMerohedral twins revisited: quinary twins and beyond
A twin is defined as being an external operation between two identical crystals that share a fraction of the atomic structure with no discontinuity from one crystal to the other. This includes merohedral twins, twins by reticular merohedry as well as coherent twins by contact where only the habit plane is shared by the two adjacent crystals (epitaxy). Interesting and original cases appear when ...
متن کاملGenetic analyses of DSM-IV nicotine withdrawal in adult twins.
BACKGROUND We examined whether there are genetic influences on nicotine withdrawal, and whether there are genetic factors specific to nicotine withdrawal, after controlling for factors responsible for risk of progression beyond experimentation with cigarettes and for quantity smoked (average number of cigarettes per day at peak lifetime use). METHOD Epidemiologic and genetic analyses were con...
متن کاملMale twins reduce fitness of female co-twins in humans.
In mammals, including humans, female fetuses that are exposed to testosterone from adjacent male fetuses in utero can have masculinized anatomy and behavior. However, the reproductive consequences of such prebirth sex-ratio effects for offspring and their implications for maternal fitness remain unexplored. Here we investigate the effects of being gestated with a male co-twin for daughter lifet...
