Sentence examples for twin environment from inspiring English sources

There were no sex differences in twin and sibling correlations (all p>.01), indicating that there were no sex differences in the heritability of BPD features, the same genes influence BPD features in men and women (test not shown in Table 3) and there is no specific twin environment (all p>.01).

A significant worsening of the model fit is indicative for a special twin environment.

Moreover, comparisons of DZ and sibling correlations showed little/no evidence for a special twin environment.

Correlations for same sex DZ and DOS twin pairs, and for sibling pairs could be constrained to be equal, suggesting that there is no evidence for a special twin environment.

We tested whether there was evidence for assortative mating, for a specific twin environment, and if the impact of the genetic and environmental factors differed between men and women and between two age cohorts.

In a correspondence exchange project between pairs of schools in the USA the project began with each child preparing a drawing and a written statement summarizing their evaluation of their own environment and an image of their "twin" environment.

The first concerns the assumption that the sharing of the monozygotic twins' environment is identical to that of dizygotic twins an assumption necessary for heritability to be estimable from twin studies.

We cannot exclude the possibility that this relates to the twin fetal environment, though the fact that HbA1c and F-glucose reflect different aspects of glucose metabolism may also be involved.

This is because the additional risk from sharing the other half of the genome would produce the same incremental contribution as that from sharing the first half, and little, if any, added environmental risk would be expected, because the commonality of MZ twins' early environment is probably only marginally greater than that of DZ twins.

These led to heritability estimates of 0.30 0.46, which are comparable to estimates obtained in the present study, but at odds with the findings in Finnish children 29 that twins' shared environment, and not genetic factors, is responsible for the similarity in LBP status.

As indicated by the pattern of MZ and DZ twin correlations, shared environment was lower when achievement was corrected for g:.30 versus.21 for teacher-rated achievement, a non-significant difference, and.20 versus.06 for tested achievement, a significant difference.
