Heritability represents the percentage in variability in a trait that comes from genetic differences. There is a great deal of evidence to show that schizophrenia is a heritable disease. It has been calculated that the heritability of schizophrenia is around 80%, and within that heritability 30% of the variability comes from single nucleotide ...
A few genetic polymorphisms such as folate hydrolase 1 and hydroxymethyltransferase 1 along with hyperhomocysteinemia were used as risk factors to develop an artificial neural network (ANN). Studies showed that this model was around 63.8% accurate in predicting ASD risk, implying a moderate association between genetic polymorphisms of the ...
The power of twin designs arises from the fact that twins may be either identical (monozygotic (MZ), i.e. developing from a single fertilized egg and therefore sharing all of their polymorphic alleles) or fraternal (dizygotic (DZ), i.e. developing from two fertilized eggs and therefore sharing on average 50% of their alleles, the same level of genetic similarity found in non-twin siblings).
[5] The study concluded that the neuroticism trait was a result of up to eighty percent of genetics. There was a stronger correlation among identical twins rather than fraternal twins. [6] The idea of biology-based personality research is relatively new, but growing in interest and number of publications. [7]

The Minnesota Twin Registry was established in 1983. [2] Its original goal was to establish a registry of all twins born in Minnesota from 1936 to 1955 to be used for psychological research. Recently, it has added twins born between 1961 and 1964.

Further, a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) should exist. This pattern is found in both strands of the DNA. This pattern is found in both strands of the DNA. They were discovered by Austrian-born chemist Erwin Chargaff [ 1 ] [ 2 ] in the late 1940s.
