Does Early Life Health Predict Schooling Within Twin Pairs? [PDF]

open access: yes
A large number of studies in labor economics estimate the returns to schooling using data on monozygotic twins, under the assumption that educational attainment is random within twin pairs. This exogeneity assumption has been commonly questioned, however,

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Chromosome 22q11.2 microdeletion in monozygotic twins with discordant phenotype and deletion size

open access: yesMolecular Cytogenetics, 2012
We report on a pair of male monozygotic twins with 22q11.2 microdeletion, discordant phenotype and discordant deletion size. The second twin had findings suggestive of DiGeorge syndrome, while the first twin had milder anomalies without any cardiac ...

A Twin Study of Genetic Contributions to Hippocampal Morphology in Schizophrenia

open access: yesNeurobiology of Disease, 2002
Our goal was to establish whether altered hippocampal morphology represents a trait marker for genetic vulnerability in schizophrenia. We outlined the hippocampi on high-resolution MR images obtained from matched samples of control and discordant ...
