Monozygotic 24-year-old twins presented with discordant ovarian function. One had had premature ovarian failure at the age of 14 years, whereas her sister had normal ovaries and three naturally con ...

The two most common types of twins are dizygotic (fraternal) and monozygotic (identical). Learn more about them and what may possibly cause multiple births.

Twin studies rest on two fundamental assumptions: 1) Monozygotic twins are genetically identical, and 2) the world treats monozygotic and dizygotic twins equivalently (the so-called “equal ...

The country's latest set of rare identical triplets headed home Monday after a month in neonatal intensive care at Houston's Memorial Hermann Southeast Hospital. Addison, Kinsley and Savannah ...

As shown in Figure 1, by 60 years of age, the cumulative incidence of diabetes among monozygotic twins who were initially discordant for diabetes was 65% (95% confidence interval [CI], 39 to 91 ...

Because monozygotic twins were thought to be genetically identical, they were perfect for sorting out which traits and illnesses have a genetic basis and which are environmentally influenced.

Just like snowflakes, no two people are alike, even if they're identical twins according to new genetic research. Scientists have been working to determine the genetic sequencing of schizophrenia ...

The epigenetic heritability may help explain currently unclear issues in human disease, such as the presence of a disease in only one monozygotic twin, the different susceptibility of males (e.g ...

Monozygotic twins with discordant karyotypes are extremely rare and usually involve the sex chromosomes. Discordance for autosomal aneuploidy has been reported for chromosomes 13 and 21. Few ...
