The most common type of study aimed at demonstrating the heritability of IQ involves comparing the two fundamentally different kinds of twins—monozygotic (MZ) or identical twins and dizygotic (DZ) or fraternal twins. The rarer MZs are the result of the fertilisation of a single ovum by a ...

Digital patterns of a sample on twins were analyzed to estimate the resemblance between monozygotic (MZ) and dizygotic (DZ) twins and to evaluate the mode of inheritance by the use of maximum likelihood based variance decomposition analysis. MZ twin resemblance of finger pattern types appears to ...
Data from individual interviews, blood grouping analyses, and ratings of photographs of a large sample of adolescent twins were examined in order to assess the accuracy of zygosity determination by alternate methods. Although the accuracy of the twins themselves and of the raters was above chance, ...

The twin-family design was used to assess social closeness between twin aunts/uncles and their respective nieces/nephews. Monozygotic (MZ) twins share 100% of their genes; therefore, MZ twins would be considered to be the genetic "parent" of their nieces/nephews. The present study is a ...
An analysis of their responses was undertaken to determine whether MZ twins were more concordant than DZ in their preferences. By discussing simple and crossed concordances, there was 68·6% concordance for MZ twins and 57·5% for DZ twins (significant at P<0·01). This lends support to the...
Conducted a comparative study with 15 pairs of monozygotic (MZ) and dizygotic (DZ) twins (aged 16–32 yrs) to determine any differences in their Level I and Level II mental abilities and personality. Level I mental abilities were assessed with the Wechsler Adult Intelligence Scale (WAIS) Digit...
As part of a recent evaluation of Colorado birth records for the years 2006 through 2008 we became aware of a shifting trend in the proportion of MZ and DZ twins in the Colorado population. Historically (Bulmer 1970 The biology of twinning in man, Clarendon, Oxford) we have expected a 1/...
