PLoS ONE, 2015 Previous studies have shown that both single nucleotide polymorphisms (SNPs) and questionnaires-based method can be used for twin zygosity determination, but few validation studies have been conducted using Chinese populations.

Noninvasive detection of twin zygosity using genome‐wide linkage disequilibrium information
Clinical and Translational MedicineDear Editor, in this study, we propose a novel linkage disequilibrium information‐based noninvasive zygosity (LDNZ) assessment method in twin pregnancies. It combines fetus‐specific allele frequency analysis with LD block to reduce the number of required

PACE Solver Description: Zygosity [PDF]
, 2023 The graph parameter twin-width was recently introduced by Bonnet et al. Twin-width is a parameter that measures a graph’s similarity to a cograph, which is a graph that can be reduced to a single vertex by repeatedly contracting twins.

A cross-sectional and prospective examination of alcohol use and misuse among adult twin and sibling pairs discordant for neighborhood socio-economic disadvantage. [PDF]
AddictionAbstract Aim To determine whether the association between neighborhood disadvantage and alcohol use and misuse can be explained by a potentially causal effect of neighborhoods or by between‐family genetic and environmental confounding. Design Cross‐sectional and prospective discordant twin and sibling study.

Anthropometric differences between twins at birth and their association with later cognitive performance. [PDF]
J Child Psychol PsychiatryBackground Past studies indicate significant associations between birth anthropometrics, such as relative birthweight or head circumference, and later cognitive performance. Using twin data, we investigated whether these associations are confounded by genetic and environmental factors.

VALIDATION OF ZYGOSITY ASSESSMENT BY A SELF-REPORT QUESTIONNAIRE IN A SAMPLE OF ADULT SERBIAN TWINS
Primenjena Psihologija, 2019 Validation of a twin zygosity-estimating questionnaire, The Questionnaire of Twins’ Physical Resemblance, created by Oniszczenko et al. and used in European and Serbian twin studies, was carried out on a sample of 222 pairs (176 monozygotic, 46 dizygotic)

ZyFISH: a simple, rapid and reliable zygosity assay for transgenic mice. [PDF]
PLoS ONE, 2012 Microinjection of DNA constructs into fertilized mouse oocytes typically results in random transgene integration at a single genomic locus. The resulting transgenic founders can be used to establish hemizygous transgenic mouse lines.
