After all, if everyone were raised in an identical environment, variations in their psychological characteristics couldn't possibly be accounted for by anything other than variations in their genes since there would be no variations in their developmental environments; the more variation in environments that twins in twin studies are exposed to, the lower the heritabilities we should expect to find. ❋ Unknown (2011)
MZ correlations were approximately twice as large as DZ correlations for all four humor styles, and univariate behavioral genetic model fitting indicated that individual differences in all of them can be accounted for entirely by genetic and nonshared environmental factors, with heritabilities ranging from .34 to .49. ❋ Unknown (2008)
He suspects that biologists, enamored of the new theory, were more likely to believe, and publish, findings of high heritabilities. ❋ Unknown (2008)
But after 1988, the heritabilities published in science journals suddenly shot up, to an average of 67 percent, finds Rauno Alatalo of the University of Jyvaskyla. ❋ Unknown (2008)
I'm not sure how they can claim autism to be the most highly genetic of all psychiatric disorders considering the well-documented heritabilities of both bi-polar disorder (which approaches the 1:2 inheritance of simple Mendelian dominance) and schizophrenia (a more complicated issue), but still, this article has a lot to offer in the way of hard nuts-and-bolts, cellular-level science-- a thing I've found lacking in many studies of autism. ❋ Kosmo (2008)
Recent findings have shown, that variation in total gray and white matter volume of the adult human brain is primarily (70-90%) genetically determined [Baare et al, 2001] and in a recent magnetic resonance imaging (MRI) brain study with 45 monozygotic and 61 dizygotic 9-year-old twin-pairs, and their 87 full siblings also high heritabilities have been found [Peper et al, in preparation]. ❋ Zoe Brain (2007)
From the rates of homosexuality observed in the monozygotic and dizygotic twins, ordinary siblings, and adoptive (adopted in) brothers and sisters of homosexual men (1, 2) and women (3, 4), overall heritabilities of 31 to 74 percent for males and 27 to 76 percent for females were estimated. ❋ Dean Hamer (1994)

The estimated heritabilities for polygenic effects and for the first and second QTL were 19%, 17% and 21%, respectively. ❋ Unknown (2009)
Detection of the second QTL in a model reduced the polygenic heritability and should improve accuracy of estimated heritabilities for both QTLs. ❋ Unknown (2009)
In practice, some caution is needed to avoid a false positive rate for detecting imprinting and maternal-zygotic interaction effects by increasing sample sizes and / or heritabilities. ❋ Unknown (2008)
Under a modest sample size and heritability, the strategy was found to be able to provide a reasonable estimation of the additive genetic and maternal-zygotic interaction effects of a QTL, but, in order to precisely estimate the dominance and imprinting effects, increased sample sizes and / or heritabilities are needed. ❋ Unknown (2008)
×F1 and P2×F1, we performed simulation studies which include several representative schemes with different imprinting degrees (none, small, mediate and large), different maternal-zygotic interaction effects (none and large), different heritabilities (0.1 and 0.4), and different sample sizes (100 and 400 for each backcross). ❋ Unknown (2008)
Estimation accuracy and precision of all the parameters can be dramatically improved with increasing sample sizes and heritabilities. ❋ Unknown (2008)
We observed moderate to high heritabilities for all traits studied in affected sister pairs, whereas heritabilities calculated from discordant siblings were substantially lower. ❋ Unknown (2008)
The genetic parameters of this QTL used to simulate the phenotypic data under different schemes are given in MLEs of the position and effect parameters for a QTL with varying imprinting effects (λ) under simulation schemes of different heritabilities (H MLEs of the position and effect parameters for a QTL without maternal-zygotic interaction effect under simulation schemes of different heritabilities (H ❋ Unknown (2008)
