Adjuvant chemotherapy has been associated with mild cognitive decline among a subset of breast cancer survivors. Late cognitive effects after chemotherapy can have a deleterious impact on survivor ...

Concordance for neuroblastoma in monozygotic twins has been reported only rarely, and the cause of the shared pathology has not been established. We describe a case of infant monozygotic twins ...

There’s a common assumption that intelligence is largely determined by genetics. After all, previously published studies ...

Monozygous twins share a common genotype. However, most monozygotic twin pairs are not identical; several types of phenotypic discordance may be observed, such as differences in susceptibilities to ...

In the study, 61 pairs of monozygotic twins where one twin is affected by MS whereas the co-twin is healthy were examined. From a genetic point of view, the twins were thus identical. "Although the ...

It is widely regarded that twins can be used as a natural experiment to subject hypotheses to empirical testing regarding the contributions of genetic factors to phenotypic variability in human traits ...

Identical, or monozygotic, twins develop from the same fertilized egg that splits into two. These twins are the same sex and share the same genes. Sometimes called paternal twins, identical twins ...

Do identical twins have the same DNA? Despite the seemingly identical DNA coding sequence, early differences in gene expression can make monozygotic twins more different than you would think. There is ...

An extremely rare set of semi-identical twins has been identified in Australia—becoming only the second ever confirmed. The "sesquizygotic" twins were identified by doctors in Brisbane while still in ...
