Heritability of Dental Caries: Twin Studies.
Vieira AR. Vieira AR. Monogr Oral Sci. 2021;30:61-70. doi: 10.1159/000520768. Epub 2022 Jan 25. Monogr Oral Sci. 2021. PMID: 35078175 Review.
The study of twins is a powerful tool to infer the presence and amount of contribution of genetic variation to a particular trait or disease. The ability to compare identical or monozygotic twins with dizygotic twins permits the direct comparison of pa …

Traces of embryogenesis are the same in monozygotic and dizygotic twins: not compatible with double ovulation.
Boklage CE. Boklage CE. Hum Reprod. 2009 Jun;24(6):1255-66. doi: 10.1093/humrep/dep030. Epub 2009 Feb 27. Hum Reprod. 2009. PMID: 19252194 Free PMC article. Review.
Embryogenesis of dizygotic twins differs from singleton development at least as much as monozygotic embryogenesis does, and in the same ways, and the differences between singletons and twins of both zygosities represent a coherent system of re-arranged embryo …

Why are there more same-sex than opposite-sex dizygotic twins?
Kanazawa S, Segal NL, de Meza D. Kanazawa S, et al. Hum Reprod. 2018 May 1;33(5):930-934. doi: 10.1093/humrep/dey046. Hum Reprod. 2018. PMID: 29534175
STUDY QUESTION: Are there more same-sex (SS) than opposite-sex (OS) pairs among dizygotic twins? SUMMARY ANSWER: In violation of Weinberg's Differential Rule, there are significantly more SS than OS pairs among dizygotic twins in nationally representat …

Unusual Twinning Resulting in Chimerism: A Systematic Review on Monochorionic Dizygotic Twins.
Peters HE, König TE, Verhoeven MO, Schats R, Mijatovic V, Ket JC, Lambalk CB. Peters HE, et al. Twin Res Hum Genet. 2017 Apr;20(2):161-168. doi: 10.1017/thg.2017.4. Epub 2017 Feb 27. Twin Res Hum Genet. 2017. PMID: 28236812 Review.
Traditionally, it is understood that dizygotic (DZ) twins always have a dichorionic placenta. However, with 8% blood chimerism in DZ twins, placental sharing is probably more common than previously has been recognized. In this article, we will review all avai …

Simultaneous occurrence of idiopathic trachyonychia in dizygotic twins.
Bibb LA, Chang MW. Bibb LA, et al. Pediatr Dermatol. 2021 Nov;38(6):1586-1587. doi: 10.1111/pde.14847. Epub 2021 Nov 1. Pediatr Dermatol. 2021. PMID: 34725852
Rarely, trachyonychia has been reported to occur in families, suggesting a potential hereditary predisposition. We report trachyonychia occurring simultaneously in dizygotic twins, further supporting a possible underlying genetic basis of this idiopathic nail disord …

Genes, environment, and personality.
Bouchard TJ Jr. Bouchard TJ Jr. Science. 1994 Jun 17;264(5166):1700-1. doi: 10.1126/science.8209250. Science. 1994. PMID: 8209250 Review. No abstract available.
Monochorionic Dizygotic Twins Conceived Spontaneously Showed Chimerism in Karyotype and Blood Group Type.
Yoshida A, Kaji T, Sogawa E, Yonetani N, Suga K, Nakagawa R, Iwasa T. Yoshida A, et al. Twin Res Hum Genet. 2021 Jun;24(3):184-186. doi: 10.1017/thg.2021.20. Epub 2021 Jun 15. Twin Res Hum Genet. 2021. PMID: 34127172
We report a very rare case of monochorionic dizygotic twins conceived spontaneously. The fetuses were sex-discordant in ultrasonography despite being monochorionic twins. ...

Lifespans of Twins: Does Zygosity Matter?
Hjelmborg J, Larsen P, Kaprio J, McGue M, Scheike T, Hougaard P, Christensen K. Hjelmborg J, et al. Genes (Basel). 2019 Feb 20;10(2):166. doi: 10.3390/genes10020166. Genes (Basel). 2019. PMID: 30791679 Free PMC article.
Studies with twins provide fundamental insights to lifespans of humans. We aim to clarify if monozygotic and dizygotic twin individuals differ in lifespan, that is, if zygosity matters. ...The population-based and oldest twin cohort ever studied suggests that monozy …

The Genetics of Human DZ Twinning.
Boomsma DI. Boomsma DI. Twin Res Hum Genet. 2020 Apr;23(2):74-76. doi: 10.1017/thg.2020.15. Epub 2020 May 8. Twin Res Hum Genet. 2020. PMID: 32383427
In the course of twin studies whose main focus was elucidation of genetic and environmental factors on behavioral traits, many twin researchers became aware of the strong tendency for dizygotic (DZ) twinning to run in families. Over four decades, Nick Martin and others ini …
