Article history: Initial receipt 2 February 2017 25 September 2017 Final revision received 25 September 2017 Available online xxxx The relationship betweenmaternal and paternal affection, reported in adulthood, and personality was examined using a genetically sensitive research design comparing differences betweenmonozygotic twins. Using life history theory as a framework, itwas predicted that ...

The expression of the H19 gene is governed by parental imprinting in mammals. H19, an unusual gene encoding an RNA with no known function, is exclusively expressed from the maternal chromosome. In mouse, it lies 90 kb downstream from the Igf2 gene, which encodes a fetal-specific growth factor, insulin-like growth factor II, and is expressed primarily from the paternally inherited chromosome. In...

We explore paternal social anxiety as a specific risk factor for childhood social anxiety in a rational optimization model. In the course of human evolution, fathers specialized in external protection (e.g., confronting the external world) while mothers specialized in internal protection (e.g., providing comfort and food). Thus, children may instinctively be more influenced by the information s...

Virtually all known cases of extrachromosomal inheritance involve cytoplasmic inheritance through the maternal line. Recently, a paternally transmitted factor that causes the production of all-male families has been discovered in a parasitic wasp. The wasp has haplodiploid sex determination: male offspring are haploid and usually develop from unfertilized eggs, whereas females are diploid and u...

Mitochondrial homoplasmy signifies the existence of identical copies of mitochondrial DNA (mtDNA) and is essential for normal development, as heteroplasmy causes abnormal development and diseases in human. Homoplasmy in many organisms is ensured by maternal mtDNA inheritance through either absence of paternal mtDNA delivery or early elimination of paternal mtDNA. However, whether paternal mtDNA...

Abstract Background Leukemia is the most prevalent childhood cancer, and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. Some epidemiological studies have shown a relationship between socioeconomic status (SES) and some childhood cancers. In the present study, an attempt was made to assess socioeconomical status in a case-control study. Materials and Methods In 2010, a c...
